In a circle, there are two chords AB and CD of equal length. They subtend angles of x° and y° at the center, respectively. Which of the following is true?
Show answer & explanation
Correct answer: C
Explanation
Chord AB = Chord CD
AB subtends an angle of x° at the center.
CD subtends an angle of y° at the center.
Since the lengths of both chords are equal, the angles subtended by them at the center will also be equal.
x = y
