Circles and their Relationship among Central Angles, Chords, and Arcs.
1a. The information you need to determine a unique circle is the coordinates of its center and radius
1b. One or more similarity transformations can be found that ma
Circles and Volume
There is something so special about a circle. It is a very efficient shape. There is no
beginning, no end. Every point on the edge is the same distance from the center. No one is
left out, everyone is the same. Without circles, we would

Arcs
The distance around the outside of a circle, the circumference, can be broken up
into many pieces. Each of these pieces is called an arc and is labeled based on its
size measured in degrees. (Remember that a circle is 360
A minor arc is an arc that i
