Question from chase, a parent:

name the regular polygon if the sum of the measures of the polygon is 1,440 and the measure of one angle is 144

Hi Chase.

A triangle's angles add to 180 degrees, a quadrilateral's add to 360 and each additional side adds another 180 degrees to the total.

So either keep adding to see when you get to 1440 or calculate it: N = (1440 / 180) + 2.

Cheers,
Stephen La Rocque.
