Honors Geometry Today’s Agenda: • YOU WILL NEED COLORS TODAY! • Homework questions?? • 1.1 Partner Activity • 1.1 Continued • Homework WARM-UP: 1. Name a point non-coplanar with plane G. 2. Name a point contained in line n. 3. Name the line that intersects the plane containing points A, D, and C. 4. Name the plane containing lines n and p. E
Expectations: • To be done in PENCIL! • Name, period, comment, and assignment at the top of the paper. • All work shown. This includes diagrams. • I expect you to check your answers at home on my webpage. (Correct you answers in a different color.) • I will grade a few problems for you to get credit. • Comment at the top in a different color. • Homework every night is worth 4 points.
Partner Practice • Please grab 1white board, 1 marker, and 1 eraser for each pair. • Have one member of the pair with their back to the projector holding the white board. • The second member facing their partner. • The person facing the white board will try to describe the picture on the board to the partner whose back is to the projector. • Then switch.
Union (È): the union of 2 or more geometric figure is the set of points of the figures Intersection (Ç): the intersection of 2 or more geometric figures is the set of points they have in common. C A B Use Colors!

EXAMPLE 4 B. Name three points that are collinear. Answer: Points A, B, and D are collinear. Example 4
EXAMPLE 4 C. Are points A, B, C, and D coplanar? Explain. Answer: Points A, B, C, and D all lie in plane ABC, so they are coplanar. Example 4
EXAMPLE 4 Answer: The two lines intersect at point A. Example 4
