|
Circle
|
A circle is 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
|
A piece of the circle.
|
|
|
Major Arc
|
More than 180 degrees. They are written with 3 capital letters.
|
|
|
Minor Arc
|
Are smaller than 180 degrees. They are written with 2 capital letters.
|
|
|
Chord
|
A line segment whose endpoints are the circle.
|
|
|
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
|
One whose sides are formed by tangents to a circle. This makes the tangent segments congruent. |
|
|
Inscribed angle
|
An angle whose: *Vertex is located on the circle. *Is made by 2 chords (or by tangent & chord) |
