The gun that measures angles are called "clinometers". We used them in Geography and maths as well! :)

Supplementary angles are 2 angles whose measures = 180o.
Two angles are complementary if the sum of their measures is 90 degrees.Two angles are supplementary if the sum of their measures is 180 degrees.

A protractor measures the degree of angles and circles.
Supplementary angles are 2 angles whose measures = 180o.
congruent angles
Two angles are complementary if the sum of their measures is 90 degrees.Two angles are supplementary if the sum of their measures is 180 degrees.
Two angles are complementary if the sum of their measures is 90 degrees.Two angles are supplementary if the sum of their measures is 180 degrees.
Congruent angles are angles that have the same measure. For example, if angle A measures 30 degrees and angle B also measures 30 degrees, then angles A and B are congruent. Additionally, angles that are vertically opposite when two lines intersect are also congruent. In general, any angles that are equal in measurement are considered congruent.
The angles in a pentagon are referred to as interior angles. In a regular pentagon, all interior angles are equal, and each measures 108 degrees. The sum of the interior angles of any pentagon is 540 degrees.
