Answers:
- In the top row, the first and third polygons are regular polygons.
- In the bottom row, only the first polygon is a regular polygon
============================================================
Explanation:
A regular polygon must have all sides of equal length. Also, all angles must be the same measure. This applies to the equilateral triangle in the upper left corner, and the square in the upper right corner. Each angle of the square is 90 degrees even though your teacher didn't use right angle markers.
The middle figure in the top row is not a regular polygon because the sides are not all the same length. Also, the angles are different.
--------------------
In the bottom row, only the first figure is a regular polygon for similar reasons mentioned earlier. The second figure is not a regular polygon because this figure is concave. Only convex polygons can be regular.
The third figure in the bottom row is not regular because one side is longer than the others.
Answer:

Answer:
(D) A circle
Step-by-step explanation:
The question says that Frank does not have a straightedge. All the options except for a circle have straight lines in them, which means that you need a straightedge to draw them. However, a circle does not require a straightedge since it has no straight lines. This shows that the only possible answer would be D (a circle).
