1. L INES AND A NGLES Chapter 3 Section 1

2. P ARALLEL L INES Coplanar lines that do not intersect. The symbol that represents them is:

3. S KEW L INES Non coplanar lines that do not intersect but are not parallel. A BC D E F G

4. P ARALLEL P LANES Planes that do not intersect

5. P AGE 141 IN THE T EXTBOOK Look at Problem 1

6. T RANSVERSAL A line that intersects two are more coplanar lines at distinct points.

7. A LTERNATE I NTERIOR A NGLES Non adjacent interior angles that lie on opposite sides of the transversal. Both are on the interior

8. C ONSECUTIVE I NTERIOR A NGLES Interior angles that lie on the same side of the transversal. Both angles will be on the interior. Are sometimes called “Same-side Interior Angles”

9. C ORRESPONDING A NGLES Lie on the same side of the transversal and in corresponding positions. One is on the interior and one is on the exterior

10. A LTERNATE E XTERIOR A NGLES Nonadjacent exterior angles that lie on opposite sides of the transversal. Both will be on the exterior

11. Consecutive Interior Angles: D, F; C, E
