Answer:
Options 3, 4 and 5 are the right answer.
Step-by-step 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 : [tex]\frac{1080}{8}= 135[/tex] 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.
