Question 3 • Geometry

Which polygon has an interior angle sum of 1080 degrees ?

Answer

A

Image with description A polygon with 10 sides and no interior angles greater than 180 degrees.

B

Image with description A polygon with 8 sides and no interior angles greater than 180 degrees.

C

Image with description A polygon with 7 sides and no interior angles greater than 180 degrees.

D

Image with description A polygon with 9 sides and no interior angles greater than 180 degrees.

Explanation

The interior angle sum of an n-sided polygon is (n − 2) × 180°. Setting this equal to 1080° gives n − 2 = 6, so n = 8. Therefore, the correct choice is the polygon with 8 sides.
