GEO Lines in the Plane 11/11/05

Today we began Ch 4 which is a short chapter on proofs and lines. We discussed detour proofs, proofs with missing diagrams, and the formula used to find the midpoint of a line segment.

-use detours in proofs
-apply the midpoint formula
-organize the information in, and draw diagrams for, problems presented in words.

p.172-174 (1,4-9,12)
p.178-179 (8,9,11)
