What is a regular polygon of 7 sides called? What is the sum of interior angles of a regular octagon?
1 AnswersA regular polygon with 7 sides is known as a heptagon. To find the sum of the interior angles of a regular octagon (8 sides), you can use the formula:
The formula for calculating the sum of the interior angles of a polygon is:
Sum = (n - 2) × 180
where n is the number of sides.
For an octagon:
Thus, the correct answer is (B) Heptagon, 1080.
