Question

Two tangents of a circle are drawn from the same exterior point, we know these 2 tangents are _______________? *

radii
Perpendicular
Parallel
Equal in length

Answer 1

Equal in length

Explanation:

The above is one of the theorems in circle or Euclidean geometry.

A tangent refers to a line that is drawn from any outside position surrounding the circle to touch the circumference of the circle i.e the length surrounding the boundary of the circle and touches the circle at exactly one point and do not enter into the circle.

Now, selecting a particular point outside the circle, serving as the exterior, of two tangents are drawn to touch the circle, then the distance from the exterior point to the two sides which the two tangent lines touch are equal in length
