How do you calculate the scale factor of a triangle?
one, use the ratio scale factor=smaller-lengthlargerlength{displaystyle {text{Scale Factor}}={frac {smallerlength}{largerlength}}}} [3] For example, if you scale from a triangle with a 15 cm base to one with a 10 cm base, you'll use the relationship scale factor=smaller-length{displaystyle {text{Scale Factor}}={frac
What is an example of a scalene triangle?
- 40 degrees - 50 degrees - 90 degrees is a scalene triangle since all the angle measures are different.
- 60 degrees - 60 degrees - 60 degrees is not a scalene triangle since the angle measures are not all different.
- 120 degrees - 10 degrees - 50 degrees is a scalene triangle since all the angle measures are different.

What is a scalene triangle?
Scalene triangles are triangles with sides of different lengths or simply a triangle with noncongruent sides. For example, a triangle of side lengths of 2 cm, 3 cm, and 4 cm can be considered a scalene triangle.
How many degrees are there in a scalene triangle?
A scalene triangle is a type of triangle with all its three sides having different lengths with the sum of three of its angles being equal to 180 degrees. It has a wide range of properties. Some of the important properties of a scalene triangle are given below. It has three sides, each of a different length.
What is the difference between a scalene triangle and an obtuse triangle?
In an obtuse scalene triangle, the circumcenter will lie outside the triangle.
What is the interior angle of a scalene triangle?
The interior angles of the triangle can be acute, obtuse, or right angles. Thus, a scalene triangle can be an obtuse-angled, acute-angled, or right-angled triangle. In the case of an acute scalene triangle, the center of the circumscribing circle will lie inside the triangle.
How many degrees does the sum of the interior angles of a scalene triangle add up to?
However, the different measurements don't affect the sum of all the interior angles of the scalene triangle. The sum of the three interior angles always add up to 180 degrees, which satisfies the angle sum property of the triangle.
What are the three types of triangles?
Triangles are classified into three types - equilateral, isosceles, and scalene triangle based on the sides. The main points of difference between these three types of triangles are as discussed below: When all the three sides of the triangles are equal in length, it is an equilateral triangle.
How many units are in a triangle?
The sides of the triangle are given as 28 units, 39 units, and 18 units. Therefore, the perimeter of the triangle = sum of the sides = (28 + 39 + 18) units = 85 units. Example 3: The length of the sides of a triangle ABC are 4 units, 3 units, and 5 units. Calculate its area.
How to Identify Scalene, Isosceles & Equilateral Triangles from Coordinates

How to Identify Scalene, Isosceles & Equilateral Triangles from Coordinates Vocabulary and Formula
Scalene Triangle: A scalene triangle is a triangle whose three sides all have different lengths, and all three angles have different values.
How many degrees does a scalene triangle have?
Scalene triangle has all its three angles different in measures and obeys the angle sum property, i.e. the sum of the three interior angles equals 180 degrees.
What are the properties of scalene triangles?
Some of the important properties of the scalene triangle are as follows: 1 It has no equal sides. 2 It has no equal angles. 3 It has no line of symmetry. 4 It has no point symmetry. 5 The angles inside this triangle can be an acute, obtuse or right angle. 6 If all the angles of the triangle are less than 90 degrees (acute), then the center of the circumscribing circle will lie inside a triangle. 7 In a scalene obtuse triangle, the circumcenter will lie outside the triangle. 8 A scalene triangle can be an obtuse-angled, acute-angled or right-angled triangle.
