Step 1
It is used to indicate that we are taking the positive square root of a number, as opposed to the negative square root. Now, let's move on to the given figure. We have a circle with chords MN and RS intersecting externally at point X. We want to prove that angle Show more…

Proof by direct proof: Theorem: If two chords intersect within a circle, then the product of the lengths of the segments of one chord are equal to the product of the lengths of the other chord. Given: Circle O with chords AR & DP intersecting at M. Prove: x · y = v · w base your proof off of the given drawing:
