If two parallel lines are cut by a transversal, then the pairs of corresponding angles are congruent. If two lines are cut by a transversal so that the corresponding angles are congruent, then the lines are parallel. If two angles are supplementary to the same angle or to congruent angles, then they are congruent.

If two lines are cut by a transversal so the consecutive interior angles are supplementary, then the lines are parallel. If two lines are parallel to the same line, then they are parallel to each other. Study with Quizlet and memorize flashcards containing terms like Converse, Parallel Lines, Transversal and more.Equality is when two things like varibles or measurements are the same numerically: 21 / 3 = 9 - 2 because when you evaluate it they're the same number (7). Congruence is when to geometric figures like lines, angles, and polygons are the same geometrically:

Line a is parallel to line b. Line c is parallel to line d. Name the transversal for each angle pair. Then tell if the angles are corresponding, alternate interior, alternate exterior, consecutive interior, or none of these. 12 and 18 _____ 20 and 21 _____How to use two column proofs in Geometry, Practice writing two column proofs, How to use two column proof to prove parallel lines, perpendicular lines, Grade 9 Geometry, prove properties of kite, parallelogram, rhombus, rectangle, prove the Isosceles Triangle Theorem, prove the Exterior Angle Theorem, with video lessons, examples and step-by-step solutions.A flow proof is just one representational style for the logical steps that go into proving a theorem or other proposition; rather than progress downward in two columns, as traditio...YZ WZ. ≅. 6.

Use this immensely important concept to prove various geometric theorems about triangles and parallelograms. Angles, parallel lines, & transversals. Parallel lines are lines in the same plane that go in the same direction and never intersect. When a third line, called a transversal, crosses these parallel lines, it creates angles. Some angles are equal, like vertical angles (opposite angles) and corresponding angles (same position at each intersection).

Imho the videos (actually there are more of them but they all resort to the same reasoning) about transversals and the ones about the sum of the angles inside a triangle are not consistent because they are circular reasoning : the "sum of angles in a triangle" starts from alleged proof of "angles in parallel lines and transversals", while these video's don't prove anything (it's taken for ... 5-8 Parallel Lines in Triangle Proofs: HW. 1.)
