To find the measure of the interior angles, we know that the sum of all the angles is 900 degrees (from above)... And there are seven angles... So, the measure of the interior angle of a regular heptagon is about 128.57 degrees.
Answer:
Explanation:
A heptagon has 7 sides. The formula for figuring out the total of the interior angles is
(sides - 2) * 180 = (7 - 2)* 180 = 5 * 180 = 900
