Question

which of the angles below is a central angle? answer ∠lci ∠jlc ∠joz ∠ljo

Explanation:

A central angle is an angle whose vertex is at the center of a circle.

• For \(\angle LCI\), the vertex \(I\) is not the center of any circle.
• For \(\angle JLC\), the vertex \(L\) is not the center of any circle.
• For \(\angle LJO\), the vertex \(J\) is not the center of any circle.
• For \(\angle JOZ\), the vertex \(O\) is the center of the left - hand side circle.

Answer:

\(\angle JOZ\)
