hey everybody i am having some trouble witht the proof. could you guys tell me where you started because i just need that something to get me on the right track
Chap, just realized what your previous post meant. Any way, not sure where to start but I will give you the first step I took in proving this problem. Start by proving two sets of the traingles congruent, the faces of the pyramid, from the givens. After that, you need something that will help you prove that all the points on MN are equal distant from AC and DB. Try adding some auxillary lines to help you prove this. If you have another question, just ask. Hope this helps.
