Parallel Lines
EQ: What angle relationships exist when parallel lines are cut by a transversal?

2. With your group…
Discuss what each of the following words mean and come up with a definition.
Alternate
Interior
Exterior
Corresponding

3. 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

4. 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

5. 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

6. Alternate Interior Angles
Angles on OPPOSITE sides of the transversal & INSIDE the parallel lines.
Alternate Interior Angles are
_______________.
Examples:
CONGRUENT
2 & 8
3 & 5

7. Alternate Exterior Angles
Angles on OPPOSITE sides of the transversal & OUTSIDE the parallel lines.
Alternate Exterior Angles are
_______________.
Examples:
CONGRUENT
1 & 7
4 & 6

8. Discuss with a partner:
If 1 = 40, name all other congruent angles.
What are the other 4 angles equal to?
                                      
4, 5, & 8
140

9. 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

10. 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.

11. Angle Pairs Stations Let’s start together…
1 = ___ because it is ________ to 140.
2 = ___ because it is ________ to  ___.
3 = ___ because it is ________ to ___.
