L INES AND A NGLES Chapter 3 Section 1

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

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

P ARALLEL P LANES Planes that do not intersect

P AGE 141 IN THE T EXTBOOK Look at Problem 1

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

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

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”

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

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

Consecutive Interior Angles: D, F; C, E
