The length of the chord AB is equal to the radius of the circle. O is the center of the circle.

The length of the chord AB is equal to the radius of the circle. O is the center of the circle. Find the degree measure for each corner of the AOB triangle.

1. Chord is a segment connecting any two points of the circle, so OA and OB are the radii of the circle OA = OB.

2. By the condition of the problem, the chord AB is equal to the radius. that is, AB = OA = OB. Therefore triangle AOB is equilateral.

3. In an equilateral triangle, all sides and all angles are equal. The angles of a triangle add up to 180⁰.

180⁰ / 3 = 60⁰, so each angle of the AOB triangle is 60⁰.

Answer: 60⁰; 60⁰; 60⁰.
