Question

prove that the radius is perpendicular to the tengent​

Answer 1

Answer:

Radius is perpendicular to Tangent

Tangent - Perpendicular to Radius. A tangent to a circle is a line intersecting the circle at exactly one point, the point of tangency or tangency point. An important result is that the radius from the center of the circle to the point of tangency is perpendicular to the tangent line.
