The title implies this is a multiple choice question, but the body of the text just describes the two polygons with no question. If you provide more info, I'm sure someone could help you out!

i have the same question, the question is indeed mutlple choice the options i have are as follows
A. The measures of all the exterior angles of Devon’s polygon are equal.
B. The sum of all the exterior angles of Devon’s polygon equals the sum of all the exterior angles
of Jamal’s polygon.
C. The measure of one of the exterior angles of Jamal’s polygon is greater than the measure of
one of the exterior angles of Devon’s polygon.
D. The measure of one of the exterior angles of Jamal’s polygon plus the measure of the adjacent
interior angle is 180°.

"A regular polygon is ... both equiangular and equilateral."; per http://mathworld.wolfram.com/RegularPolygon.html. The Pentagon in Washington is a regular 5-gon. Stop signs are regular octagons. Equilateral triangles are regular trigons. Squares are regular 4-gons.

I agree, the question does not ask for the difference in  sides of the polygons, as far as regularity both are regular , but different sides.

So 14 sides and 15 sides are both regular polygons of different sides, why the statement is not true.
