hw #4-2 Due Thurs Nov 11
1) Read pgs 122-23
2) pg 124 #1-25 ALL

Your GEOMETRY BIBLE should be complete through SAS, ASA, SSS... include defs of cgrt triangles and cgrt polygons

4-3  Using Congruent Triangles

hw #4-3 Due Mon Nov 15
1) Read pgs 127-128
2)
pg 130 #1-16 ALL
3) pg 132 #1-5,7

IF #1-16 seems like too much, at least do the ODDS... Some friendly advice from your nasty teacher... practice on these proofs will pay off down the road!

GB should include def. and sketch of a line and a plane that are perpendicular
