For example, a polygon with three sides is called a triangle.

A polygon with four sides is called a quadrilateral.

A polygon with five sides is called a pentagon.

• Polygons that have all sides measure the same are called regular polygons.

                                                   

Examples of Polygon

The figure shows a few polygons.

Solved Example on Polygon

Identify the set hat shows the polygons arranged in the decreasing order of number of sides.

Choices:

A. Octagon, hexagon, pentagon, and quadrilateral

B. Pentagon, hexagon, octagon, and quadrilateral

C. Quadrilateral, pentagon, hexagon, and octagon

D. Hexagon, pentagon, quadrilateral, and octagon

Correct Answer: A

Solution:

Step 1: The number of sides of quadrilateral, hexagon, pentagon, and octagon are 4, 6, 5 and 8 respectively.

Step 2: Decreasing order means arranging from the greatest to the least.

Step 3: The decreasing order of the polygons with respect to the number of sides is octagon (8), hexagon (6), pentagon (5), and quadrilateral (4).
