A set of points that are the same distance from one fixed point called the center of the circle.
|
|
|
Radius
|
A line segment from the center of the circle to any point of the circle
|
|
|
Central Angle
|
An angle formed by 2 Radii. The vertex is on the center point.
|
|
|
Arc
|
An Arc is a piece of the circle.
|
|
|
Major Acrs
|
Are more than 180 degrees. They are written with 3 capital letters.
|

Minor Arcs
|
Are smaller than 180 degrees. They are written with 2 capital letters.
|
|
|
Chord
|
A line segment whose endpoints are the circle.
Note: It may go through the center, but it doesn't have to. |
|
|
Diameter
|
A chord that goes through the center.
|
|
|
Tangent
|
A line that intersects the circle in exactly one spot. When a radius connects at the tangent, the angle formed is a right angle.
|
|
|
Circumscribed Angle |
Is one whose are formed by tangents to a circle, this makes the tangent segments congruent. |
|
|
Inscribed Angle |
An angle whose: Vertex is locatd on the circle and is made by 2 chords (or by tangent and chord) |
