Question

1. △pqr≅△xyz. list three pairs of angles that are congruent.
2. △abc≅△jkl. list three pairs of sides that are congruent.

Explanation:

Step1: Recall congruent - triangle property

If $\triangle PQR\cong\triangle XYZ$, corresponding angles are congruent.

Step2: List angle - pairs

$\angle P\cong\angle X$, $\angle Q\cong\angle Y$, $\angle R\cong\angle Z$

Step3: Recall congruent - triangle property for sides

If $\triangle ABC\cong\triangle JKL$, corresponding sides are congruent.

Step4: List side - pairs

$AB\cong JK$, $BC\cong KL$, $AC\cong JL$

Answer:

1. $\angle P\cong\angle X$, $\angle Q\cong\angle Y$, $\angle R\cong\angle Z$
2. $AB\cong JK$, $BC\cong KL$, $AC\cong JL$
