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.
