... geometric figures. I can apply the concepts of congruence to solve problems. I can prove relationships in geometric figures (i.e. prove triangles and corresponding parts are congruent). I can determine and justify when two triangles are congruent (including ASA, SAS, AAS, HL and SSS Theorems). ...

Discovery of Non-Euclidean Geometry
... (a) Let Σ1 be the set of points Y ∈ r(Q, R) such that the ray r(P, Y ) does not meet l, and Σ2 the complement of Σ1 in QR. It is easy to see that both Σ1 , Σ2 are convex. So Σ1 , Σ2 form a Dedekind cut of QR. Then there exists a unique point X ∈ QR such that Σ1 , Σ2 are two rays (one of them is an o ...
