Shmoop video We Will Rock U Parallel Lines EQ: What angle relationships exist when parallel lines are cut by a transversal?
With your group… Discuss what each of the following words mean and come up with a definition. Alternate Interior Exterior Corresponding
Look at the bottom of the GO… In the diagram, lines m and n are called_______________ lines. Line l goes through the parallel lines. This is called a _______________. PARALLEL TRANSVERSAL
Graphic Organizer Vertical angles are across from each other and share a common vertex. They are ____________. Give some examples. A Linear pair of angles are ______________ and _____________. CONGRUENT ADJACENT SUPPLEMENTARY
Corresponding Angles CONGRUENT 1 & 5 2 & 6 4 & 8 3 & 7 Angles that are in the same position and same side of the other parallel line. Corresponding Angles are ______________. Examples: CONGRUENT 1 & 5 2 & 6 4 & 8 3 & 7
Alternate Interior Angles Angles on OPPOSITE sides of the transversal & INSIDE the parallel lines. Alternate Interior Angles are _______________. Examples: CONGRUENT 2 & 8 3 & 5
Alternate Exterior Angles Angles on OPPOSITE sides of the transversal & OUTSIDE the parallel lines. Alternate Exterior Angles are _______________. Examples: CONGRUENT 1 & 7 4 & 6
Discuss with a partner: If 1 = 40, name all other congruent angles. What are the other 4 angles equal to? 4, 5, & 8 140
To summarize… Find the missing angles in the “Elephants” worksheet. Remember to give the relationship/reason you found each measure. You may work with a neighbor. Day 2
4/8/15 Please take out your HW worksheet. Please check. All you need is the parallel lines GO from yesterday, a piece of paper, and a pencil. Please fold the paper in quarters.
Angle Pairs Stations Let’s start together… 1 = ___ because it is ________ to 140. 2 = ___ because it is ________ to ___. 3 = ___ because it is ________ to ___.
