Class Tue. 11/23

In class we worked on the computer lab packet "Introduction to The Geometer's Sketchpad (Day 2)."

Students who were absent: You can get this packet from FirstClass, and see the previous post for information about accessing the software.

Students who were present: if you didn't finish the proofs at the end of the lab, it's recommended that you finish them tonight while today's activity is fresh in your mind.

There's no homework over the vacation. Happy Thanksgiving!

Lab Mon. 11/22 and HW due Tue. 11/23

Monday's class: We worked on a computer lab, "Introduction to The Geometer's Sketchpad." (If you were absent so need to make up this lab, you can get the handout from FirstClass, and you can download a preview copy of the software with limited features which might be sufficient to get you through the assignment. Otherwise you'll need to work on a computer at school or you can buy a software license for $14.95.)

Homework due Tuesday: Proof problems on page 5 of the computer lab handout (you don't need computer software to do the homework).

HW due Mon. 11/22

On pp. 242-248, read Chapter 6 Lesson 6 "AAS and HL Congruence." Do exercises 11-50 and Set III.
