Which of the following is a regular polygon.
1. rectangle
2. circle
3. equilateral triangle
4. trapezoid
I want to say it " equilateral triangle"
you are right
You are correct! The equilateral triangle is a regular polygon. It is a polygon with three equal sides and three equal angles.
You are correct! The equilateral triangle is indeed a regular polygon. To determine this, we need to understand what a regular polygon is.
A regular polygon is a polygon that has equal side lengths and equal angle measures. In the case of an equilateral triangle, it has three equal sides and three equal angles. Each angle of an equilateral triangle measures 60 degrees.
If we analyze the other options:
1. Rectangle: A rectangle is not a regular polygon because it has opposite sides of equal length, but the other two sides are not equal.
2. Circle: A circle is not a regular polygon because it is a curved shape with no sides or angles.
4. Trapezoid: A trapezoid is not a regular polygon because it has two parallel sides, but the other two sides are not equal in length.
By considering the characteristics of regular polygons, we can conclude that the equilateral triangle is the only regular polygon among the given options.
