Explain why pqr is an equilateral triangle

PQ is a radius, as it reaches the center and an edge. So is PR, just in a different location. They are the same length because the edges of a circle is equidistant from the center. Given that circle P is congruent to circle Q, QR is a radius that is the same length as the two other sides. So, all of the sides have the same lengths. That means that the triangle is equilateral.
