Two Angles are Supplementary when they add up to 180 degrees. They don't have to be next to each other, just so long as the total is 180 degrees. Examples: 60° and 120° are supplementary angles. 93° and 87° are supplementary angles.

noun, Mathematics. 1. either of two angles that added together produce an angle of 180°. Compare complementary angle. It may be noted that ∠P2CP1, being made up of halves of two supplementary angles, is a right angle. supplementary angle.

Angle is also used to designate the measure of an angle or of a rotation. This measure is the ratio of the length of a circular arc to its radius. In the case of a geometric angle, the arc is centered at the vertex and delimited by the sides. In the case of a rotation, the arc is centered at the center of the rotation and delimited by any other point and its image by the rotation.

In planar geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle. Angles formed by two rays lie in a plane, but this plane does not have to be a Euclidean plane.

Nov 14, 2015. Angles with a sum of 180 degrees. Supplementary angles are angles whose sum is 180 degrees. An example would be two angles that are 50 and 130. Their sum is 180 degrees, and they form a straight like when put together.

Two angles are supplementary if the sum of their angles equals 180o. If one angle is known, its supplementary angle can be found by subtracting the measure of its angle from 180o. Example: What is the supplementary angle of 143o? Solution: 180o - 143o = 37o.

Parts of an Angle. The arrows on the sides of the angle tell you that you can extend the sides (These are called rays). The space between the two rays (the two sides) is what we call an angle. The point where the two rays meet is called the vertex. An angle separates a plane into three parts: the interior of the angle, the exterior of the angle, and the angle itself.

The two angles will change so that they always add to 180°. In the figure above, the two angles ∠PQR and ∠JKL are supplementary because they always add to 180°. Often the two angles are adjacent, in which case they form a linear pair like this: Similar in concept are complementary angles, which add up to 90°. Sometimes it's hard to remember which is which between supplementary (adds to 180°) and complementary (adds to 90°).

Complementary or Supplementary Angles. Two angles are complementary if the sum of their angles equals 90o. If one angle is known, its complementary angle can be found by subtracting the measure of its angle from 90o.
