# what are segment proofs

In an axiomatic treatment of geometry, the notion of betweenness is either assumed to satisfy a certain number of axioms, or defined in terms of an isometry of a line (used as a coordinate system).

Defi nition of congruent segments STUDY TIP When writing a proof, organize your reasoning by copying or drawing a diagram for the situation described. With very few exceptions, only teaching jobs require such skills as ability to prove geometric theorems. Given: TP B: Prove that when a transversal cuts two paralle l lines, alternate interior and exterior angles are congruent. In the above diagram, the angles of the same color are equal to each other. $$\overline{AB}$$ is the tangent passing through the point P. The tangent makes $$\angle \alpha$$ with the chord PQ. Theorems include: vertical angles are congruent; when a transversal crosses parallel lines, alternate interior angles are congruent and corresponding angles are congruent; points on a perpendicular bisector of a line segment are exactly those equidistant from the segment's endpoints. 7.
