# Parallel lines cut by a transversal doodle notes

• Pairs of Lines and Angles Section 3.1 notes. Parallel Lines and Transversals Exploring Parallel Lines and a Transversal. Have students use Geogebra to construct two parallel lines and a traversal. They then identify and measure corresponding, alternate interior, alternate exterior, and consecutive interior angles and make conjectures.
THEOREM-4 :- If a transversal intersects two parallel lines, then each pair of consecutive interior angles are supplementary. Given : AB and CD are two parallel lines. Transversal “t” intersects AB at P and CD at Q, making two pairs of 2 consecutive interior angles, 1, 2 and 3, 4. To Prove : (i) 1 + 2 = 180° and (ii) 3 + 4 = 180°

transversal intersects two parallel lines. Review/read the theorems and postulate one more time. Then… The notes in the next foldable will help you sum up all the information and give yourself hints of how to write equations related to parallel lines and transversals.

Tape one set of parallel lines being cut by a transversal on the floor for each student in your class. These will need to be pretty big. I make mine cover a 3 foot by 3 foot square. If you have a larger Geometry or PreAlgebra class put the students in groups of 2 and have them take turns.

Consequently, angle D = angle F and angle G = angle E. Parallel Lines Cut by a Transversal When two parallel lines are cut by a transversal (i.e., a third line intersects the two parallel lines), a number of relationships exist between the resulting angles.

Theorem: If three parallel lines cut congruent segments off a transversal then, they cut off congruent segments on every transversal. Corollary: A line that contains the midpoint of one of the sides of a triangle and is parallel to another side bisects the third side of the triangle.

Parallel lines Task Goal: Create a banner illustrating all of the angle pairs associated with parallel lines. ( Ikr.Þars/ Search on the internet for parallel lines cut by a transversal algebra questions (just like the ones we completed in class). You will need to find one question that deals with each of the following angle

geometry of parallel lines and the knowledge of how to prove that lines are parallel is a significant aspect of the work that these people do. . Recap the postulate and 3 theorems about parallel lines and transversals that we learned in the previous lesson. Corresponding Angles Postulate: If two lines cut by a transversal are parallel,

Coplanar lines that do not intersect are called parallel Lines that are not coplanar and do not intersect are called skew When two lines are cut by a transversal, there are many special angle relationships formed when considering both lines Special angle pairs: on the same side of the transversal are consecutive interior or consecutive exterior on opposite sides of the transversal are alternate interior or alternate exterior
Parallel Lines Cut By A Transversal. A line cutting across another line is a transversal. When a transversal cuts across lines suspected of being parallel, you might think it only creates eight supplementary angles, because you doubled the number of lines.
