Answer:
Step-by-step explanation:
Given are two triangles ABC and XYZ.
We have AB = XY = 25 cm, AC = YZ = 29 cm
and also angle A = angle X = 36 degrees
Thus we find that corresponding congruent sides are
AB and AC with angles A and X
To map ABC onto xyz,
Vertex B to Y, side AB to side XY with AC coinciding with XZ
Now all vertices x,y,z will perfectly match with transformed ABC
