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).
