1. SECTION 3.3 Angles Formed by Transversals
VOCABULARY
Transversal
Corresponding Angles
Alternate Interior Angles
Alternate Exterior Angles
Same-Side Interior Angles
LEARNING TARGETS:
Students will be able to identify corresponding angles, alternate interior angles, alternate exterior angles, and same-side interior angles.

2. NOTE: Today is a big vocabulary day!
It is important that you take good notes so that when we introduce new Theorems about these vocabulary words they will make sense.

3. Vocabulary
TRANSVERSAL:
A line that intersects two or more coplanar lines at different points.
For instance, in the diagram below, the blue line t is a transversal.
The angles formed by two lines and a transversal have special names.

4. Angle Pairs
As stated before, angles formed by two lines and a transversal have special names.
We will use the diagram below to help us identify all of the different types of angle pairs.

5. Vocabulary CORRESPONDING ANGLES:
Angles that occupy corresponding (matching) positions.

6. Vocabulary ALTERNATE INTERIOR ANGLES:
Angles that lie between (on the inside of) the two lines and are on the opposite sides of the transversal.

7. Vocabulary ALTERNATE EXTERIOR ANGLES:
Angles that lie outside of the two lines and are on the opposite sides of the transversal.

8. Vocabulary SAME-SIDE INTERIOR ANGLES:
Angles that lie between (on the inside of) the two lines and are on the same side of the transversal.
