Angles in Polygons

Triangle has 3 sides and the sum of interior angles are 180 (180 x 1)

Quadrilateral has 4 sides and the sum of interior angles are 360 (180 x 2)

Pentagon has 5 sides and the sum of its interior angles are 540 (180 x 3)

Hexagon has 6 sides and the sum of its interior angles are 720 (180 x 4)

The exterior angles of a polygon add up to 360 degrees.

To find out what you have to times 180 by, just minus 2 from the amount of sides and voila!
