1. Sketch an example in the Hyperbolic Half-plane of a quadrilateral with three right angles. (You will have to estimate the third angle.) Does the fourth angle appear to be acute, right or obtuse?

2. Sketch an example in the Hyperbolic Half-plane of two parallel lines cut by a transversal so that corresponding angles are not congruent.

3.Prove the Hypotenuse-Leg triangle congruence theorem
