Question

Two arcs of a circle are congruent, the ratio of their corresponding chords is ______.

Options

• 1 : 1

• 1 : 2

• 1 : 3

• 1 : 4

Answer 1

Two arcs of a circle are congruent, the ratio of their corresponding chords is 1 : 1.

Explanation:

Congruent (equal) arcs subtend equal central angles; equal central angles in the same circle cut off equal chords.

Therefore, the corresponding chords are equal, so the ratio is 1 : 1.
