Hannah's post for May 2, 2011

So today we started on chapter 10, which is all about angles in a circle.

For starters, some words that we need to know are:

1. chord: a line segment with both endpoints on a circle

2. central angle: an angle formed by two radii of a circle

3. inscribed angle: an angle formed by two chords that share a common point

4. arc (of a circle): a portion of the circumference

We drew four different diagrams in class. All of which involving a circle.
They're subtended by the same arc. In other words, they share a common end point.

Homework for tonight is..
  • read pg. 382 Key Ideas
  • CYU #1
  • Practice and apply
  • Extend 18, 19, 20
  • Extra Practice
  • Homework book
