What is the size of the angle? Draw a polygon that has the same interior angle.
The size of the angle is not specified in the question, so let's assume an angle of 120 degrees.
A regular pentagon has interior angles of 108 degrees each, which is close to 120 degrees. Here is the drawing of a regular pentagon:
