6. Has four equal sides and four right angles, each corner meets at 90 degrees.
8. Has three sides and three angles, can be classified as equilateral, isosceles, or scalene.
9. Round and without any corners, every point on its edge is the same distance from the center.
12. Similar to a square but with two pairs of equal sides, it also has four right angles.
13. With six sides and six angles, it can also be regular or irregular based on the equality of sides and angles.
14. Has four sides with one pair of parallel sides, can be isosceles or scalene.
15. Comprised of eight sides and eight angles, often seen in traffic stop signs.

5. Its opposite sides are parallel and equal in length, creating two pairs of congruent angles.
