Note: It is possible for a right triangle to also be scalene or isosceles
Isosceles triangle
In geometry, an isosceles triangle is a triangle that has two sides of equal length. Sometimes it is specified as having two and only two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case.
Does a right triangle always have to be scalene?
A right triangle is scalene if all three sides are a different length such as one with sides of 3, 4 and 5. You can have an isosceles right triangle with two sides the same length such as a 1, 1 and 2 sided triangle.An equilateral right triangle (all three sides equal) is not possible.
Is it possible to make a right isosceles triangle?
and In isosceles triangle two sides are equal. Let us consider a right triangle ΔPQR. Now, For a right angled triangle PQR to be isosceles. We make two sides of a right triangle equal. Since PR is hypotenuse i.e. the longest side. Hence, it can’t be equal to any other side. Thus, other two sides are equal. ∴ PQ = PR.
What are the angles of a perfect scalene triangle?
The properties of the right scalene triangle are listed below:
- All three sides are different in measurements.
- All three angles are different in measurement with one angle of 90 degrees.
- The sides are in relation: Hypotenuse 2 = Perpendicular 2 + Base 2.
- The side opposite to the right angle is the longest side known as hypotenuse.
- The sum of all the interior angles is 180 degrees.
Is it possible for Triangle to have two right angles?
So, no it cannot have 3 or even 2 right angles. No, real, triangle can have three right angles. For a set of vertices and sides to be a real triangle, two things must be true. The sum of the angles formed must equal 180° and the sum of the length of two sides must be greater than the length of the third.
What is an acute triangle?
An acute triangle has all angles measuring less than 90º. Note: It is possible for an acute triangle to also be scalene, isosceles, or equilateral. Note: It is possible for a right triangle to also be scalene or isosceles. An obtuse triangle has one angle measuring more than 90º but less than 180º (an obtuse angle).
Do all scalene triangles have a right angle?
A scalene triangle can have a right angle, or an angle with measure 90°, but not all scalene triangles have a right angle.
Is a scalene a polygon?
No, a scalene triangle is not a regular polygon. All the triangles are polygons and are characterised by having three sides.
What are right angle scalene triangles?
Right angle scalene triangles are triangles that are scalene and have a right angle at the same time. A triangle is a right triangle when it has an angle that measures 90 degrees. On the other hand, a scalene triangle is a triangle that has all of its sides of different lengths and all of its interior angles of different measures. These triangles share the same main characteristics as all other triangles, that is, the sum of their interior angles is equal to 180 degrees . The following is an image of a right angle scalene triangle:
What are the most important formulas for solving scalene triangles with right angles?
The most important formulas for solving problems with scalene triangles with right angles are the area formula, the perimeter formula, and the Pythagorean theorem.
How long is a scalene triangle?
A scalene triangle has sides of lengths 12 m, 15 m, and 17 m. What is the perimeter?
Which theorem can be used to find the length of a triangle?
Since the triangle has a right angle, we can use the Pythagorean theorem to find the length of one side if we know the length of the other sides:
How long is the third side of the sandstone?
The length of the third side is 10 m.
What is scalene triangle?
In scalene triangles, all sides are of different lengths and so all angles will be of different magnitudes.
What is the ratio of the length of height of a scalene triangle?
The ratio of the length of height of a scalene triangle is 3:4:5. The longest side of triangle is 12 cm. What is the perimeter of the triangle?
How to find the ratio of lengths of sides?
The ratio of lengths of sides are in inverse proportionality to the ratio of their respective lengths of height (as area of triangle ∆= (1/2)ah¹= (1/2)bh²= (1/2)ch³ where a,b&c are respective sides with the corresponding heights as h¹,h² & h³=> a=2∆/h¹,b=2∆/h² & c=2∆/h³ ). Hence the corresponding sides of the ∆, with the given ratio of heights, are in the ratio (1/3): (1/4): (1/5).assuming the constant of proportionality to be k=> their lengths would be (k/3), (k/4), (k,5). So perimeter will be (k/3)+ (k/4)+ (k/5)=47k/60. From the empirical lengths the longest being (k/3)=12=> k= 36.So the perimeter =47k/60=> perimeter=47×36/60=28.2cm. Ans
How many degrees are there in a right triangle?
No. Right triangle has one 90 degree and two 45 degree angles. And that means two angles are the same size. Scalene triangle is a triangle where no angles are the same and al of the sides are different lengt. For example you have triangle with 60, 40 and 80 degree angle.
Is a right angle triangle a scalene triangle?
A right-angle triangle says nothing specifically about line lengths of the lines. So obvious;ly a right-angle triangle is also a scalene triangle. Unless it isn’t.
Is a right triangle scalene?
Most of the time, right triangles are scalene triangles. Since it is possible for the other two angles to both be 45°, this will make the right triangle an isosceles triangle instead. So whenever at least one of the other angles is not 45°, then it will be a scalene triangle.
What angle is above Accra?
A second right angle. And if you were almost above Accra, it should be clear that you will have a third right angle.
How many sides does a scalene triangle have?
À scalene triangle has 3 sides that are all of different lengths; a right scalene triangle will have a right angle (90 degrees) and the other 2 angles may not be congruent, nor shall either of the other two sides be congruent. 206 views.

What is the name of the triangle with one right angle and two other angles that are not equal?
An example would be the famous 3,4,5 pythagorean triangle, that looks like this: It describes most right-triangles. It’s a triangle with one right angle and two other angles which are not equal. Every right angled triangle that is not a scalene has two 45 degree angles.
How many 45 degree angles are there in a right angled triangle?
Every right angled triangle that is not a scalene has two 45 degree angles.
Is an equilateral right triangle possible?
An equilateral right triangle (all three sides equal) is not possible.
Can an isosceles triangle have two sides?
You can have an isosceles right triangle with two sides the same length such as a 1, 1 and 2 sided triangle. An equilateral right triangle (all three sides equal) is not possible. À scalene triangle has 3 sides that are all of different lengths; a right scalene triangle will have a right angle ...
What is a right scalene triangle?
ANSWER: A right triangle is a triangle with a right angle (90°). A scalene triangle is a triangle which has no two sides equal. So a right scalene triangle is a triangle with a right angle and with no two sides equal.
How to check if a triangle is right angled?
We can use Pythagoras' Theorem to check if a triangle is right-angled, using the following method: Square the two shorter sides and add the values together. Square the longest side. Check if the results for (1) and (2) are the same.
What is the obtuse angle of an equilateral triangle?
Explanation: The angles in an equilateral triangle are all 60 degrees. An obtuse angle is greater than 90 degrees. 60< 90 so an equilateral triangle can not have an obtuse angle.
What are the different types of triangles?
What are the types of triangle? The sum of angles in any triangle is 180°. An equilateral triangle has three equal sides and angles. An isosceles triangle can be drawn in many different ways. A right-angled triangle has one 90° angle. A scalene triangle has three different angles and none of its sides are equal in length.
What is the angle of a right triangle?
In a right triangle, one of the angles is a right angle—an angle of 90 degrees. A right triangle may be isosceles or scalene. In an acute triangle, all angles are less than right angles—each one is less than 90 degrees. An acute triangle may be equilateral, isosceles, or scalene.
How to find the area of an isosceles triangle?
To find the area of an isosceles triangle using the lengths of the sides, label the lengths of each side, the base, and the height if it's provided. Then, use the equation Area = ½ base times height to find the area.
