Vocabulary Radius Chord Diameter Arc Center
Center and Arc B C — A A circle can be named by its center. A circle with a center labeled C would be named circle C. An unbroken part of a circle is called an arc.
Radius A radius connects the center with a point on the circle.radius CD D C —
A chord connects two points on a circle. chord AB— B — A
diameter A diameter is a chord that passes through the center of a circle. diameter AB A — — B

1 Lesson 10.2 Arcs and Chords. 2 Theorem #1: In a circle, if two chords are congruent then their corresponding minor arcs are congruent. E A B C D Example:
The outside of the circle is called circumference The circumference is the distance around the circle.
Circles and Chords. Vocabulary A chord is a segment that joins two points of the circle. A diameter is a chord that contains the center of the circle.
