Question

The angle between two coincident tangents to a circle

Answer 1

The angle between two coincident tangents to a circle=0 degree

Step-by-step explanation:

Let a circle with center O.

AB and EF are  two tangents on the circle.

When tangent AB and EF are coincident that means all point lie on AB are also lie on EF or AB and EF superimpose to each other.

We know that when two lines are parallel then the angle between two parallel lines =0 degree

When two lines are coincident it means the lines are parallel.

Therefore, two tangents are parallel.

The angle between two coincident tangents is equal to 0 degrees.
