UNDERSTAND Special pairs of angles areformed byparallel lines that cut a transversal. In the diagram, line j is parallel to line k, line t is a transversal, and the 8 angles formed are labeled 1 through 8 . Angles 1 and 5 form a pair of corresponding angles. They lie on the same side of the transversal, and Model with Mathematics Draw a pair of parallel lines cut by a transversal. Estimate the measure of one angle and label it. Without using a protractor, label all the other angles with their approximate measure. \$16:(5 Lines m and n are parallel and cut by the transversal p Which of the following pairs of angles represent corresponding angles?

lines cut by the transversal are parallel. Because each angle is 35 °, then we can state that a ll b.

Parallel Lines And Transversals Project Answer Key ... Students will review the concepts of parallel lines and several angles. Students will use Geogebra or constructions by hand to visualize the properties of parallel lines, transversals and angles formed. About This Quiz & Worksheet. When a transversal crosses two parallel lines, eight angles (and four different kinds of angles) are formed. Your knowledge of these angles will be tested with this quiz. The top angle will be 90-55 = 35 The bottom left angle will be 90 The bottom right angle will be 180-x 35 + 90 + (180-x) = 180 125 + 180 - x = 180 125 - x = 0 125 = x. If two lines are parallel, their consecutive interior angles sum to 180. In this case, angles 2 and 3 are consecutive interior angles.

In a plane, lines will either intersect (cross) or be parallel. If 2 lines are cut by a transversal, certain angles are formed and have relationships. Interior Angles: Angles on the inside of the lines. Exterior Angles: Angles on the outside of the lines. Adv. Math Geometry Review W. 11-19 Page 3 of 21

then the lines are parallel. Theorem 3.7: (The Alternate Interior Angles Converse) If lines are cut by a transversal so that a pair of Alternate Interior Angles are congruent, then the lines are parallel. Theorem 3.8: (The two perpendiculars are parallel theorem) If two lines are perpendicular to the same third line, then the two lines are parallel.

parallel lines are cut by a transversal, and the angle-angle criterion for similarity of triangles. For example, arrange three copies of the same triangle so that the three angles appear to form a line, and give an argument in terms of transversals why this is so. Transversal - a line that intersects two lines to form eight angles 4_ transversal Interior Angles: £3, L4 L5, 16 (inside parallel lines) Exterior Angles: L 1, 12, L7 £8 (outside parallel lines) Alternate Interior Atwles - Interior angles found on opposite sides of the transversal. When two parallel lines are cut by a transversal the ...

when a transversal intersects parallel lines. Construct a line and label two points on the line A and B. Create point C not on ‹ __ › AB . Then construct a line parallel to ‹ __ › AB through point C. Create another point on this line and label it D. A B 8.G.1.5 8.G.1.5 Use informal arguments to establish facts about… the angles created when parallel lines are cut by a transversal… . Angle Pairs Formed by a Transversal Term Example Parallel lines are important when you study quadrilaterals because six of the seven types of quadrilaterals (all of them except the kite) contain parallel lines. The eight angles formed by parallel lines and a transversal are either congruent or supplementary. Check out the above figure which shows three lines that kind of resemble a giant […]

When a line crosses two parallel lines (a transversal), a whole new level of angle relationships opens up: [insert drawing of left-to-right parallel lines AR and TO intersected by transversal DI. Point Y is along AR; Point L is along TO; the whole figure spells ADROITLY in a circular way] Improve your math knowledge with free questions in "Transversals of parallel lines: find angle measures" and thousands of other math skills.

In the Key Concept, students learn that the terms apply to any two lines cut by a transversal, and then learn in Part 2 that special relationships exist for parallel lines. Consequently, students gain tools for finding unknown angle measures and are more prepared to develop geometric proofs.
