1 Bellwork Do the following problem on a ½ sheet of paper and turn in. The ratios of three angles in a triangle are 8:6:4. Find the value of x and classify the triangle by sides and angles.

2 7.2 Two Proof Oriented Triangle Theorems Students will be able to apply the AAS and No Choice Theorems.

3 No Choice Theorem Toolbox! Prove: If two angles of one triangle are congruent to two angles of another triangle, then the third angles are congruent. An Algebraic Proof:

4 Example 1 Given: Prove: VBYZ is a parallelogram.

5 Example 2 Given: O is the center Prove:
