Question

what is the measure of an angle made by a tangent and the radius of a circle at the point of contact? ​

Answer 1

The measure of the angle made by a tangent and the radius of a circle at the point of contact is 90°.

Step-by-step explanation:

• Let O be the centre of the circle drawn in the given picture and OP be the radius of length r.

• If the tangent AB meets the circle at P, then we can say that OP is perpendicular to AB at P.

• Mathematically, we express it as OP ⏊ AB.

Answer 2

The measure of an angle made by a tangent and the radius of a circle at the point contact is 90°
