Question

consider the circle with center at point $o$. determine the information you need to show that $overset{\frown}{rq} cong overset{\frown}{st}$.

enter the answer in the space provided. use capital letters.

$square cong square$

Explanation:

In a circle, two arcs are congruent if their corresponding central angles are congruent, or if their corresponding chords are congruent. To prove $\widehat{RQ} \cong \widehat{ST}$, the key required information is that their corresponding chords are congruent, or their central angles are congruent. The most direct chord-based condition is that chord $RQ$ is congruent to chord $ST$.

Answer:

$RQ \cong ST$
