euclidean geometry step by step process 1. (7 pts) Prove that the diagonals of a rectangle are congruent. 2. (18 pts) In the diagram below, prove that M is the midpoint of AC and BD if and only if ABCD is a parallelogram. 3. (9 pts) Use #1 and #2 above to prove that the diagonals of a square cut each other into 4 congruent segments. Use #3 to prove that the diagonals of a square are angle bisectors of...

12. In Theorem 4.1 it was proved in neutral geometry that if alternate in- terior angles result in hyperbolic geometry by proving that the lines are parallel, i.e., that they have a common perpendicular. (Hint: Let M be the midpoint of transversal segment PQ and drop perpendiculars MN and ML to lines m and l; see parallel. Strengthen this divergently are congruent, then the lines are Figure 6.23. Prove that L, M, and N are collinear by the method of...
