Explanation:

Step1: Identify the first polygon

It is a triangle. Triangles have 3 sides, no parallel sides, and in this case 1 right - angle (since it is a right - triangle).

Step2: Identify the second polygon

It is a pentagon. Pentagons have 5 sides. In a regular pentagon, there are no parallel sides and no right - angles.

Step3: Identify the third polygon

It is a square. Squares have 4 sides, 2 pairs of parallel sides, and 4 right - angles.
