Geometry: Students completed the process of proving that certain properties exist in a parallelogram.
They then were given a worksheet that required them to work backwards; instead of being given a parallelogram and proving its properties, they were given properties of a figure and were required to prove that this figure is a parallelogram.

Homework:  Finish the proofs you did not finish in class.

Pre-Calculus:
Today's Link
We started section 7.4 by completing some problems that required the use of the sum and difference formulas.  They then proceeded to working on a GSP activity that took up the rest of the hour.  The activity required them to find cos(a+b) and sin(a+b) on the unit circle.

Homework: Finish the packet up to Question ...........
