Answer:
Step-by-step explanation:
If two triangles are equal, it means that the ratio of the length of each side of one triangle to the length of the corresponding side of the other triangle is constant. Also, corresponding angles are congruent.
1) Triangle TUV is similar to triangle SQR because
Angle Q is congruent to angle U
TU/SQ = UV/QR = 2
2) Triangle ABC is not similar to triangle DEF because the ratio of AB to DF is not constant.
