Answer 1

Answer:

Tangent line perpendicular to radius

The radius of a circle is perpendicular to the tangent line through its endpoint on the circle's circumference. Conversely, the perpendicular to a radius through the same endpoint is a tangent line. The resulting geometrical figure of circle and tangent line has a reflection symmetry about the axis of the radius.

Answer 2

Answer:

Tangent line is perpendicular to the radius....

The radius of the circle is perpendicular to the tangent line through its end point on the circle's circumference.... Conversely, the perpendicular to the radius through a same and the point is the tangent line.... The resulting geometrical figure of the circle and the tangent line has a reflection symmetry about the axis of the radius
