Maths homework helps?!?

I will tell you that the sum of all the angles inside a polygon with x sides is 360, and that the sides of the polygon are all equal. A polygon has the same number of sides as it has angles; a triangle has 3 sides and 3 angles, a rectangle has 4 sides and 4 angles, etc. Finally, the sum of the interior angle and it's adjacent exterior angle is 180.
