Answer:
Option A true is the answer.
Explanation:
The given circle there are two arcs AB and CD.
Angles formed by these arcs at the center arc 30°
Formula of length of arc = r × θ
where r = radius of the circle
and θ = angle formed by arc at the center.
mAB = OA × (30°) [ By formula ]
similarly mCD = DC × (30°)
Since OA = OC = r (radii of the circle )
So mAB = mCD
Therefore, statement is true.
Option A true is the answer.
