CHAPTER 3: PARALLEL LINES AND PLANES 3-1: DEFINITIONS PIB GEOMETRY

3-1 WARM UP: DRAW A PICTURE. HOW MANY DIFFERENT WAYS COULD… 1.Two lines not intersect? 2.Two planes not intersect? 3.A line and a plane not intersect?

LINES Two lines that do not intersect are either skew or parallel

LINES AND PLANES Can two planes be parallel? Can a line and a plane be parallel?

NAMES OF ANGLES Interior angles: Exterior angles: Corresponding Angles: Alternate Interior Angles: Same-Side Interior Angles:
