Question

Which of the following statements apply to a polygon with eight sides? i. It is a hexagon ii. It is a heptagon iii. It is an octagon iv. It has a total interior angle measure of 1,080º v. Each interior angle is 135º

Answer 1

Options 3, 4 and 5 are the right answer.

Explanation:

A polygon with eight sides is called an octagon.

The sum of the interior angles of an octagon is 1080 degrees. In octagon, all sides are congruent and all interior angles are congruent.

The measure of the interior angle of a regular octagon is 135 degrees.

We can find this by :
`(1080)/(8)= 135` degrees.

The correct options are :

iii. It is an octagon

iv. It has a total interior angle measure of 1080 degrees.

v. Each interior angle is 135 degrees.

Answer 2

I think the correct answers among the choices listed above are options iii, iv and v. A polygon with eight sides is referred as an octagon. Each interior angle is 135º and when all of the interior angles are added it will sum up to 1,080º
