The true statements about the circle are;

  • mArc C B = 120°
  • m∠COB = 2(m∠CAB)
  • m∠COB = 120°

What is a line segment?

A line segment is known to be a kind of line that has two endpoints. It is said to have endpoints and some other points of the line found between them.

The angle intercepted on opposite side of the circle from an ARC is one that measure of half of the Arc.

Note that ∠CBA is half of the ARC CA.

∠CAB is given as 60°

So 60*2 will give you mArc C B = 120°. The same method is applicable to m∠COB = 120°
