The two tangent theorem states that given a circle, if P is any point lying outside the circle, and if A and B are points such that PA and PB are tangent to the circle, then PA = PB.
It follows from Power of a Point trivially, or we can use similar triangles, given that tangents to a circle form a right angle to the radius to the point of tangency.
