 Hello and welcome to the session. Today I will help you solve this question. The question says, what is a regular polygon? State the name of a regular polygon of three sides, four sides and six sides. So let's see the solution. A polygon with equal sides and equal angles is called a regular polygon. Now, if the number of sides of the polygon is three, then that regular polygon is called an equilateral triangle and a polygon with number of sides as four is called a square and a polygon with number of sides as six is called a regular hexagon. Hence, our final answer in this case is a polygon with equal sides and equal angles equilateral triangle, regular hexagon. Hope you enjoyed the session. Have a good day.
