Question

The lengths of tangent drawn from an external point to a circle are equal.

• A. True
• B. False

Answer 1

The correct option is A True

The triangles formed by radius tangents and distance from exterior point to center are congruent by $RHS$ criteria

Since,

1) Radius is same

2) The angle between radius and tangent is ${90}^{\circ }$

3) The distance from center to exterior point is also same.

So by corresponding parts ,

The lengths of tangent drawn from an external point to a circle are equal
