Answer:
Dilation and reflection
Step-by-step explanation:
To have two congruent triangles you need to have:
1-Two angles and the sides between them respectively congruent
2-Two sides and the angle between them respectively congruent
Or
3- three sides respectively congruent
In every case of dilation we wont have any side congruent to the initial triangle, so neither 1, 2 or 3 will be true.
