Homework Help: Geometry- how to write proof

Posted by Jen on Friday, February 23, 2007 at 1:19pm.

ABC is a right triangle. Angle C is 90 degree.
Altitude CD is drawn to hypotenuse AB.

Prove AB/BC = BC/BD and AB/AC = AC/AD

This is a theorem. How do I prove it? Thanks.

Dont you have similar triangles? You can show this by looking at the angles involved...remember the altitude forms a perpendicular angle on the hypotenuse.
