 05:55 PM #1, i've been having a bit of trouble with geometry proofs. Plan: (I'm not sure if this is detailed enough? I'm really trying to learn and figure this one out myself, but I could use a little guidance. If the other two angles add to 90, and the first angle is 90, then each of the other two angles must be the same. CA and CDB are congruent right angles - definition of altitude.

#### Proofs, in, geometry, help Thanks in advance for your help! Permalink, raw Message, i need help with a few proofs. Assume that any two of visual analysis essay definition the centers O,G, H,I coincide. AC is congruent to, bC - definition of isosceles triangle. I'm only given one line to write on, so I don't think they expect a full paragraph proof.) Prove that triangle CAD is congruent to triangle CDB, then that point D is the midpoint. C, d A and CDB are congruent right angles - definition of altitude. CD bisects ACB - perpendicular bisector theorem. Also, # 2, 3 and 4 need more information than the diagrams show. If someone could look it over and tell me what I should fix/improve, that would be great.
