During today's block we began our detailed approach to the relationships and properties of parts of circles. We started with a vocabulary review (p 70:1-8,20, p 306:1-9) using the notes sheet from last week to guide our work.

Grades were taken for HW #4 & 5 if not already done (4 pts each).

After sharing the warm-up, we paid attention to being very careful and precise with the marks used in naming parts of circles. For example: arc PQR is not the same as angle PQR nor is either the same as triangle PQR. The symbols are important!

We took notes on C-54-60 over chord and tangent properties. We used a deductive approach to determine why each is true. We recorded enough information in our notes to be able to figure out the homework and write up our conjectures.

The handout below has the homework listed as well as instructions on what to write and sketch in Geometric Truth. Follow instructions carefully.

On your homework, you only need to show enough work to figure out what you put in your calculator. The best approach to the homework is to use the conjectures to figure how what you should be seeing in the sketches. So when you are asked to say which conjecture or definition tells you how to solve the problem, just put down the conjecture number that helped you figure out the problem.
