Question

A regular polygon with 10 sides is known as:
A. Heptagon
B. Decagon
C. Septagon
D. Octagon

Answer 1

Hint: The given problem is related to shapes and their names. Try to recollect the names of various polygons and the number of sides that they have.

Complete step-by-step answer:

A polygon is any 2-dimensional closed figure formed with straight lines. Triangles, quadrilaterals, pentagons, and hexagons are all examples of polygons. The name tells you how many sides the shape has. For example, a triangle has three sides, and a quadrilateral has four sides. So, any shape that can be drawn by connecting three straight lines is called a triangle, and any shape that can be drawn by connecting four straight lines is called a quadrilateral.
Polygons with sides of equal lengths are called regular polygons. For example: A square has all its sides equal. Hence, it is a regular polygon.

The word Heptagon has the word “hept” , which means 7. The word Decagon has “deca”, which means 10. The word Septagon has “sept”, which also means 7. The word Octagon has “Octa”, which means 8.
Therefore, the regular polygon of 10 sides is known as decagon.

Note: Remember the names of the polygon for the respective number of sides. Students may face difficulties if they are not able to remember the names of the polygon. These confusions can result in wrong answers. So, the names of the polygons must be remembered properly.
