which of the fawlowing is a regular polygon a. rectangle b. circle c.eaqulatiral triangle or d.trapizoid pls help me asap
unless it's equilateral or equiangular it's not regular
To determine which of the following options is a regular polygon, you need to understand the characteristics of a regular polygon.
A regular polygon is a polygon with all sides of equal length and all angles of equal measure.
Let's analyze each option to determine if it meets the criteria of a regular polygon:
a. Rectangle: A rectangle has four sides, but its angles are not all equal. Therefore, it is not a regular polygon.
b. Circle: A circle is not a polygon since it does not have straight sides. Therefore, it is not a regular polygon.
c. Equilateral triangle: An equilateral triangle has three sides of equal length and three angles of equal measure. This meets the criteria of a regular polygon. Therefore, an equilateral triangle is a regular polygon.
d. Trapezoid: A trapezoid is a quadrilateral with at least one pair of parallel sides. Its sides are not all equal in length, so it is not a regular polygon.
Based on the analysis above, the option that represents a regular polygon is c. Equilateral triangle.
