Question

which two triangles are congruent? complete the congruence statement.

Explanation:

Step1: Identify congruence criteria

By observing the markings on the triangles, we see that $\triangle BCD$ and $\triangle XYZ$ have two - sides and the included - angle equal. This is the Side - Angle - Side (SAS) congruence criterion.

Step2: Write the congruence statement

The vertices must be matched correctly. So, $\triangle BCD\cong\triangle XYZ$.

Answer:

$\triangle BCD\cong\triangle XYZ$
