-5.1: Come up with triangle sum conjectures, draw any triangle and combine it's angles to make a line. Problems: 1-5, 7
-5.2: What is an isosceles triangle? Do the two conjectures. Notice how we have shown that equal angles in isosceles means equal sides and vice versa. Check out the paragraph proof for equiangular triangles on 234 and do the final conjecture. Problems: 1-7 (Photocopy page to do this assignment)
-5.3: DO THE INVESTIGATION 5.3.1: problems 1-13 do odds only
-5.4: Investigation 5.4.1, 5.4.2, 5.4.3 and the conjectures. Do 1-10
-5.5: Investigation 5.5.1, 5.5.2, 5.5.3 and the conjectures. Do 1-10
-5.6: 1-11 odds
Then do 2-8 even
-5.7: Do conjecture C-37. Then do 1-4, 7 on page 267
Pythagorean Theorem Intro:
10.1: Do investigation 10.1 as a class. Construct a right triangle and show that A^2+B^2=C^2 using area. Then do 10.1 1-12 even on page 479.

10.2 Do 1-5, 15, and 17 on 483
10.3: Do 1, 8-11 on page 485
