What is the result when two radii are drawn in a circle?

When two radii are drawn in a circle, they indeed form an isosceles triangle with the center of the circle being one vertex and the endpoints of the radii on the circumference being the other two vertices. This is because both radii are equal in length, as all radii in a circle are defined to have the same measurement from the center to any point on the circumference.

In an isosceles triangle, at least two sides are of equal length, which is the case here, making it the correct description of the triangle formed by the two radii and the line segment connecting their endpoints on the circle.
