The central angles are congruent, then GH and JK are congruent. Hence, the given statement is true.
What is a sector ?
A sector is formed by two radii and the intercepted arc on the circle.
The angle subtended by the sector at the center is said to be Central Angle.
Given statement is;
"Given circle O below, the arcs GH and JK must me congruent."
We know that if they are congruent the angle subtended by them at the center will be equal.
The measure of ∠GOH = 80 degree
The measure of KOJ = 80 degree.
Therefore , ∠KOJ = ∠GOH = 80 degree
Since the central angles are congruent, then GH and JK are congruent.
Hence, the given statement is true.
