New cards
Arc of a Circle
The portion of the circumference between two points on the circle.
2
New cards
Central Angle
An angle whose vertex is at the center of the circle and whose sides pass through the circle's circumference points.
3
New cards
Arc Length
The distance along the circle circumference between two points.
4
New cards
Ratio of Central Angle to Whole Circle
The simplified fraction representing the central angle relative to the total angles in a circle (360 degrees).
5
New cards
Arc Length Formula
L = (θ/360) * 2πr, where L is arc length, θ is the central angle, and r is the radius.
6
New cards
Circumference of a Circle
The total distance around a circle, calculated as C = 2πr.
7
New cards
Proportionality of Arc Length and Central Angle
The measure of an arc length is directly proportional to the ratio of its central angle to the entire circle.
8
New cards
Fraction of Circle Circumference
A way to express a part of the circumference as a ratio relative to the whole circumference.
9
New cards
Sector of a Circle
The area bounded by two radii and the arc connecting them.
10
New cards
Simplest Fraction
A fraction that cannot be reduced any further, representing the lowest form of the ratio.
