In the figures δcda ≅ δxyz, name the congruent sides.

CD is congruent to XY
DA is congruent to YZ
CA is congruent to XZ

Explanation:
When writing congruent triangles, the order of writing the letters is very important. This is because each side/angle in the first triangle is congruent to its corresponding side/angle in the second triangle.

Now, we are given that:
ΔCDA ≅ ΔXYZ
Following the order of letters, we can find that:
angle C = angle X
angle D = angle Y
angle A = angle Z
CD = XY
DA = YZ
CA = XZ

Hope this helps :)
