The radii, the tangents, and the line from P to the center of the circle form two congruent right triangles.  The tangent segments from P to the points of tangency with the circle are one of the pairs of corresponding sides in those two triangles, so they are congruent.<br>
The two radii and the two tangents form a quadrilateral with two pair of adjacent sides, making it a kite.<br>
