... Any triangle is defined by six measures (three sides, three angles). But you don’t need to know all of them to show that two triangles are similar. Various groups of three will do. Triangles are similar if: 1. AAA (angle, angle, angle): All three pairs of corresponding angles are the same. 2. SSS in ...

... The measure of an interior angle of a regular polygon is 140 find the number of sides in the polygon. Use formula S = 180(n-2) S = 140n If one angle is 140, then sum is 140 times the number of sides. 140n = 180(n-2) Plug into formula 140n = 180n-360 Simplify 360 = 40n n=9 ...
