This is going to sound very confusing, because I don't have a picture to show. I'll try my best to explain.
Okay, so I have a picture of a circle with the center point O and diameter AOH. There are 5 chords that are inside of the circle. One of them, labeled MT, crosses the circle, intersecting the diameter AOH. This makes an "X" shape almost, but MT does not cross through the middle of the circle. The other 4 chords outline connect the tips of the "X" shape. So the tips of the X are on the circumference of the circle, and are labeled M, A, T, H clockwise. O is the midpoint of the circle. Z is where chord MT hits the diameter AOH.
I have to prove that
(MZ)/(ZH) = (AZ)/(ZT)
I don't remember the rules to prove this. If you don't understand my explanation of the picture, and simple rules to prove things about circles would be very helpful. Thanks!
