| What is the a radius? | Half of the diameter of a circle |
| What is a diameter? | The full length across the middle of a circle |
| How do you find circumference? | Two times pi times the radius (2nr) |
| What is the measure of the angle if given the arc? | If central angle, they are the same. If inscribed angle, the arc divided by 2 |
| How do you find the measure of a pair of adjacent angles when given the arcs on both sides? | Average the two arcs |
| What is an inscribed angle | An angle where the vertex is on the side of the circle instead of the middle |
| What is a central angle | An angle who's vertex is in the middle of the circle |
| What are tangent angles | angles who's vertex lies outside of the circle, and the lines cross at one point on the sides of the circle |
| How many degrees are in half of a circle (Semicircle) | 180 |
| How many degrees are in an entire circle | 360 |
| To find the measure of a tangent angle you... | Subtract the smaller arc from the larger arc and divide by 2 |
| What is a major arc | An arc that is greater than 180 |
| What is a minor arc | An arc that measures less than 180 |
| What are concentric circles | Circles that lie in the same plane, and share the same midpoint |
| What is a semicircle | Half of a circle |
| What is circumference | Distance all of the way around the circle |
| What is a chord | A line whos endpoints are on the edge of a circle |
| How do you find the diameter of a circle | Multiply the radius by 2 |
| What is a circle | When all points are the same length apart from the center |
