Question

I understand rigid motions but I just need a little guidance on how to prove that ABC is congruent to figure EFG

Answer 1

Step-by-step explanation:

Rigid motion include translation, rotation and reflection. Every part of the figure is involved in the transformation. Considering figure ABC and EFG, they have congruent lengths and angles. To prove congruency, they need to coincide. To do that, the first step is

Translate point A so that it coincides with point E. After this is done, the next step is to rotate point C until it coincides with G. This would make B to coincide with F. Thus, ABC coincides with EFG. Therefore,

ABC is congruent to figure EFG
