John Morris FRCR John. \(\overline{AB}\) is the tangent passing through the point P. The tangent makes \(\angle \alpha\) with the chord PQ. By the symmetric property of equality, XY = PQ. Substitution Property: If two geometric objects (segments, angles, triangles, or whatever) are congruent and you have a statement involving one of them, you can pull the switcheroo and replace the one with the other. Then identify the Given and Prove statements. The best videos and questions to learn about Proofs. A paragraph proof is only a two-column proof written in sentences. This video from Yay Math!
