question 14 of 25
if $angle abc$ measures $90^circ$, what is the measure of $overarc{ac}$?
a. $90^circ$
b. $180^circ$
c. $45^circ$
d. $270^circ$

Explanation:

Step1: Identify central angle property

The measure of a central angle is equal to the measure of its intercepted arc.

Step2: Match angle to arc

$\angle ABC$ is the central angle intercepting $\widehat{AC}$, so $m\widehat{AC} = m\angle ABC$.
<Expression>
$m\widehat{AC} = 90^\circ$
</Expression>

Answer:

A. $90^\circ$
