Do intersecting chords form a pair of vertical angles? How do you find the angle of intersecting chords? What happens when two chords intersect? This video explains the theorem behind angles of intersecting chords, how to calculate the angles of intersecting chords, and how to use algebra to solve for variables in intersecting chord math problems.
One little note- at 10:11, when I say "x=30", I mean 30 degrees, and the other arc is 60 degrees. I'll admit I can be bad about dropping units. Oops 😶
