Step-by-step explanation:

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 2

HEXAGON:

hexagons

Using the same methods as for hexagons to the right

To find the sum of the interior angles of

a heptagon, divide it up into triangles... There are five triangles... Because the sum of the angles of each triangle is 180 degrees... We get
