If triangle QRS is congruent to triangle XYZ, what are 2 pairs of congruent sides and 2 pairs of congruent angles?

QRS congruent to XYZ,

Look for congruent sides by the corresponding letters, example,

QR is congruent to XY

QS is congruent to XZ, and RS is congruent to YZ.

Same idea with angles,

angles QRS and XYZ are congruent,

angles RSQ and YZX are congruent, etc.
