Question

Find the sum of the interior angles of the dodecagon show work .

Answer 1

1800

Explanation:

By the Polygon Interior Angles Sum Theorem, the sum of the measures of the interior angles of a n sided convex polygon is (n-2)180.

A do-decagon has twelve sides. The sum of its interior angles will be (12-2)*180=10*180=1800.

Answer 2

[insert carefully drawn regular dodecagon]

Sum of interior angles = (n-2) x 180° Sum of interior angles = 10 x 180° = 1800°
