Sides Of A Right Triangle
- the side PQ, which is opposite to the right angle PRQ is called the hypotenuse . The hypotenuse is the longest side of the right triangle.
- the side RQ is called the adjacent side of angle θ.
- the side PR is called the opposite side of angle θ.
How do you find the unknown side of a triangle?
How do you find the unknown side of a triangle? The Pythagorean theorem states that a2 + b2 = c2 in a right triangle where c is the longest side. You can use this equation to figure out the length of one side if you have the lengths of the other two. The figure shows two right triangles that are each missing one side’s measure.
How to find opposite side of triangle?
sin α a = sin γ c and sin β b = sin γ c. Collectively, these relationships are called the Law of Sines. sin α a = sin β b = sin γ c. Note the standard way of labeling triangles: angle α (alpha) is opposite side a ; angle β (beta) is opposite side b ; and angle γ (gamma) is opposite side c . See Figure 10.1.6.
What is an adjacent interior angle of a triangle?
The interior angles of a triangle always add up to 180° while the exterior angles of a triangle are equal to the sum of the two interior angles that are not adjacent to it. Another way to calculate the exterior angle of a triangle is to subtract the angle of the vertex of interest from 180°.
How to find the missing sides and angles of a triangle?
Step by step guide to finding missing sides and angles of a Right Triangle
- By using Sine, Cosine or Tangent, we can find an unknown side in a right triangle when we have one length, and one angle (apart from the right angle).
- Adjacent, Opposite and Hypotenuse, in a right triangle is shown below.

What are adjacent sides examples?
Adjacent sides are sides of a polygon that have a common vertex. Usually found in triangles and other polygons, two of the sides that meet at a vertex of the polygon are called adjacent sides. In other words we can say, in geometry, two sides that meet to create an angle are said to be adjacent.

What is called adjacent side?
If two sides share a common angle, then they are called adjacent sides.
What is the opposite and adjacent sides of a triangle?
it is also the longest side in the triangle. Adjacent and opposite sides are in respect to the angle asked and can vary accordingly. Opposite side is the side that is opposite to the angle asked for and the adjacent side is the side that is right by the angle that is asked for.
Does adjacent mean side by side?
As in common use, the word adjacent in geometry refers to adjacent (side-by-side) elements to each other in shape. Usually applied to lines, arcs, or angles. In trigonometry, the adjacent side of a right triangle is the side following the angle.
What is hypotenuse and adjacent?
"Adjacent" is adjacent (next to) to the angle θ "Hypotenuse" is the long one.

What are two adjacent sides?
Any two sides of a polygon with a common vertex (corner point).
What are the pairs of adjacent sides?
Two sides of a quadrilateral which have a common end point are called its adjacent sides. In the given figure, (AB, BC), (BC, CD), (CD, DA) and (DA, AB) are four pairs of adjacent sides of quadrilateral ABCD. Two sides of a quadrilateral are called its opposite sides if they do not have a common end point.

What are adjacent angles?
The two angles are said to be adjacent angles when they share the common vertex and side. The endpoint of the rays, forming the sides of an angle, is called the vertex of an angle. Adjacent angles can be a complementary angle or supplementary angle when they share the common vertex and side.
What is the adjacent side of a rectangle?
A rectangle is a four-sided closed polygon. The opposite sides of a rectangle are parallel and equal. The adjacent sides of the rectangle are always perpendicular to each other. In a rectangle one side is shorter while its adjacent side is longer.
How do you find adjacent angles in a triangle?
How do you identify adjacent angles? Being able to identify a common side and a common vertex is the simplest way to identify an adjacent angle. If two angles share one side and both derive from the same corner (vertex) point, then they are adjacent angles.
