Question

which two triangles are congruent? complete the congruence statement.

Explanation:

Step1: Identify congruent - side and angle markings

By observing the side - length markings (single, double, triple) and angle - marking (curved lines), we can see that $\triangle RST$ and $\triangle BCD$ have corresponding equal sides and angles.

Step2: Write the congruence statement

The order of vertices matters. Since the corresponding parts match, we have $\triangle RST\cong\triangle BCD$.

Answer:

$\triangle RST\cong\triangle BCD$
