1. What do you think would make a term defined as opposed to undefined?
Warmup
What do you think would make a term defined as opposed to undefined?
SWBAT: Understand defined terms in relationship to undefined terms.
SWBAT: Understand and apply the Angle Addition Postulate.

2. Defined Terms vs. Undefined Terms
The following list of terms fall into two categories: Defined terms and undefined terms:
Angle, Point, Circle, Complementary, Perpendicular Line,
Parallel Line, Line, Line Segment, Plane, Supplementary.
Undefined terms
Defined terms

3. Copy down the definitions for the following defined terms
Write out a sentence explaining why we need undefined terms:
Copy down the definitions for the following defined terms
Angle: A figure formed by two rays with a common endpoint. *Do you know the name for this endpoint?*
Circle: The set of all points equidistant to the center.
Complementary:
Line Segment: A part of a line that is bounded by two distinct end points.
Perpendicular Line:
Parallel Line:
Supplementary:
