Complex Polygon –Complex polygon is a polygon whose sides cross over each other one or more times. Sum of Angles of a Polygon 1. Sum of the interior angles of a polygon: Sumof the interior angles of a polygon with n sides = (n – 2) × 180° ...
To find the sum of the interior angles a + b + c, we note that the angle x, formed between the triangle and the parallel top line, is alternate to b, hence b = x. Likewise, c = y. We can also see that x, a, and y join together on the straight line, hence a + x + y...
