Question

In a geometry class, Nazia is asked to draw a concave octagon. She draws a closed figure with eight sides. The sides are not equal in length. The greatest interior angle measure is 190°, and the least interior angle measure is 75°.

Which statement about the figure Nazia draws is true?

Answer 1

She draws a correct figure because an interior angle measures more than a straight angle.
She draws a correct figure because no interior angle measures more than a straight angle.
She draws an incorrect figure because an interior angle measures more than a straight angle.
She draws an incorrect figure because no interior angle measures more than a straight angle.

Answer 2

it's C or D.

Answer 3

She draws a correct figure because an interior angle measures more than a straight angle.

This octagon is interesting because it is concave and not convex.

I used an online tool to draw such a concave octagon.
