Area of a Circle and a Sector — Unit test

Question 3 • *CR CCSS Math 2 S2 [M2960OX]

Which is true regarding secants and chords?

Answer

Chords intersect the perimeter of a circle at two points. Secants intersect the perimeter of a circle once.

Chords intersect the perimeter of a circle at one point. Secants intersect the perimeter of a circle twice.

Chords and secants intersect the perimeter of a circle twice. Chords are segments entirely within a circle, while secants are lines or rays that extend through a circle.

Explanation

A chord is a line segment whose endpoints lie on the circle, so it meets the circle’s perimeter at two points and stays within the circle. A secant is a line or ray that passes through the circle, meeting its perimeter at two points as well. Choice C gives both definitions correctly; choice D reverses them.
