3  Unit Circle Quiz  Trig Values Quiz  These will be important again in Chapter 5

4 Section 6.1

5  Think back to geometry. Write down the ways to prove that two triangles are congruent.

6  An oblique triangle does not contain a right angle.  Can be separated into two right triangles.

7  For a triangle with angle measures A, B, C and side lengths opposite those angles of a, b, c:  True for every triangle (acute, right, obtuse)

14  Page 607 #1-13 Every Other Odd  Page 608 #17-29 Every Other Odd  Page 608 #33-45 Every Other Odd

15  Find all angles θ in the interval [0, 360°) such that

16

17  Given two side lengths and an angle opposite one of them, there could be 0, 1, or 2 triangles

18

19  Assume a, b, and A are given  If, then there are no triangles  If, then there is one right triangle  If, then there are two triangles  If, then there is one triangle  The Law of Sines will give you the number of triangles

20  Solve the triangle
