Question 7 • *CR CCSS Math 2 S2 [M2960OX]

Which is true regarding chords and diameters of circles?

Answer
A
Both chords and diameters have two endpoints on a circle. Diameters must intersect the center of a circle.
B
Both chords and diameters have two endpoints on a circle. Chords must intersect the center of a circle.
C
Chords have two endpoints on a circle. Diameters have one endpoint on a circle and one at the center.
D
Chords have one endpoint on a circle and one at the center. Diameters have two endpoints on a circle.

Explanation

A chord is a line segment with both endpoints on the circle. A diameter is a special chord that passes through the circle’s center, so it also has two endpoints on the circle. Therefore, the true statement is that both have two endpoints on the circle and diameters must intersect the center.
