Question

Please help! This is past due, and I’m a little confused.

For problems 12-15, name each of the polygons represented by the traffic signs. Write yes or no whether the polygon appears to be regular.

Answer 1

12. Octagon, Regular

13. Triangle, Regular

14. Rectangle, Irregular

15. Pentagon, Irregular

Explanation:

Irregular vs. regular boils down to whether the sides and angles of the figure are all equal. In figures 14 and 15, the sides are clearly not all the same length, so they are irregular.
