Geometry:
We continued our discussion of the Hinge Theorem and also talked about how to complete an Indirect Proof, showing the steps working on a couple proofs we had on the worksheet.

Homework: Finish the worksheet that requires you to complete indirect proofs. Come to class tomorrow prepared to discuss them.


Pre-Calculus:
We started Chapter 7, talking about trigonometric identities.  We discussed which segments in a unit circle related to the six trig ratios.  We also discovered which trig functions were even or odd.  We then finished our discussion by talking about the Negative-Angle Identities.

Homework: Verify that these negative-angle identities are true based on the unit circle.
