Based on the tangent theorem, the angle formed by the radius and a tangent to a circle is: 90 degrees.
What is the Tangent Theorem?
Based on the tangent theorem, when a tangent and a radius of a circle intercept at a point along the circumference of the circle, the angle formed there is a right angle.
A right angle equals 90 degrees. Therefore, the angle formed by the radius and a tangent to a circle measures: 90 degrees.
