WebExample 2: l and m are two parallel lines, P is the transversal. Find the measures of angle A and angle B. Solution: It is given that the lines, l and m are parallel intersected by the transversal P. Thus, we can say that a = b (alternate interior angles). Also, a + 140° = 180° (pair of supplementary angles). WebNotes: PROOFS OF PARALLEL LINES Geometry Unit 3 - Reasoning & Proofs w/Congruent Triangles Page 165 IF THEN Corresponding angles are congruent. Alternate interior angles are congruent. Alternate exterior angles are congruent. The lines are PARALLEL Consecutive interior angles are supplementary. The lines are perpendicular to the same line. EXAMPLE …

If the sum of the interior angles α and β is less than 180°, the two straight lines, produced indefinitely, meet on that side. In geometry, the parallel postulate, also called Euclid 's fifth postulate because it is the fifth postulate in Euclid's Elements, is a distinctive axiom in Euclidean geometry. mavebeauty reviews

"WebProof: To prove this result, we will consider the vertically opposite angle of ∠1. Here, the vertically opposite angle of ∠1 is ∠3. So, ∠1 = ∠3 (vertically opposite angles) Here, line AB CD, ∠3 = ∠7 (corresponding angles axiom) ∴∠1 = ∠7 (transitivity) Hence, proved.

WebProof. This construction works by creating a triangle and then translating (sliding) the triangle along the given line. All corresponding vertices of a translated polygon are linked by lines that are congruent and parallel. This can be seen more clearly in the animation at Translating a Polygon.
