Chapter 4 Open Book Review
Triangle Congruence by ASA
and AAS: apply properties,
definitions, and apply
properties, definitions, and
theorems of two dimensional
figures to solve problems, plan
and write proofs
Chapter 4 Test
Congruent Triangles
(Closed Book)
Assignment: Review notes,
especially definitions,
properties, postulates, and
theorems; Do p.233:11-39 (odds)
Assignment: Write a proposal
with sample diagrams of a
“Rules Review Game” for
definitions, properties,
postulates, and theorems.
The game should include the
wording of each rule; an
example of how to apply each
rule; and rules for how to play
and “win” the game
