• Homework Help · 10 years ago. math: proving lines parallel worksheet help? Derive the slope of line L from the equation m = (y2-y1)/(x2-x1) Derive the slope of line M from x- y = 6 with the aid of adjusting to the slope-intercept variety, y = mx -c. In the two situations the slope is one million, no...

• Prove Theorem 1. There exists at least one path. Note that Axiom 3 guarantees the existence of an ant, but no axiom explicitly states that there is a path. We need to prove the theorem to prove the existence of a path. Proof. By Axiom 3, there exists an ant.
• Construct parallel lines. Prove theorems about parallel lines. Use the Transitive Property of Parallel Lines. Using the Corresponding Angles Converse Theorem 3.5 below is the converse of the Corresponding Angles Theorem (Theorem 3.1). Similarly, the other theorems about angles formed when parallel lines are cut by a transversal have true converses.
• • For lines GH and KP, taking CD as transversal, ∠2 and ∠3 are corresponding ∠’s. If these angles are equal, then lines are parallel. ∠2 = 57°, ∠3 = 55° ∠2 ≠≠≠ ∠3. Since corresponding angles are not equal, therefore, GH is not parallel to KP. • Similarly, for lines EF and KP, taking CD as transversal ∠1 and ∠3 ...
