In a geometry class, Brian is asked to draw a concave hexagon. He draws a closed figure with six sides. The sides are not equal in length. The greatest interior angle measure is 150°, and the least interior angle measure is 85°.

Which statement about the figure Brian drew is true?

He draws a correct figure because it is a regular polygon.

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

He draws an incorrect figure because the sides are not equal in length.

He draws a correct figure because one interior angle measures more than a str

the last answer says "He draws a correct figure because one interior angle measures more than a straight angle."

A concave polygon has atleast one interior angle greater than 180 degrees (straight angle). like this:|dw:1340818345198:dw|

But, since the greatest angle he drew was 150 degrees in measure, it was definitely not a CONCAVE polygon.
And also, regular polygons have all sides and interior angles equal in measure.
So, it wasn't regular either.
