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.
