 Question 174585: My teacher assigned a problem called Dilcue's Chair. She said that it required some research to answer and I have tried to research the answer online all week and I have found nothing. The problem says that the chair was built such that the legs, segment HN and segment AO are attached at their midpoint R. Even though the legs turn out to be unequal in length, the seat of the chair, segment HA, is parallel to the floor, segment ON. Can you please help me solve this problem? Thank You.

 Question 175611: Hi All, I'm a HS Senior with my last class in Geometry, I saw a problem similar to mine, but with a different fact to prove...so here it is: Prove:If an isosceles triangle has an altitude fron the vertex to the base, then the altitude bisects the vertex angle Given:(triangle)ABC is isosceles; (line) CD is the altitude to base (line) AB To Prove: (line)CD bisects (angle) ACB Plan: (this space is blank, what should I write here? It's slightly confusing) What I do know now is that two sides are congruent, and the altitude creates two right angles. This is all pretty confusing to me, math isn't my strong suit.
