Question

Geometry

Answer 1

In an isometry, the lengths remain the same, and the polynomials are congruent.

Answer 2

So, what does that give you to look for in the illustration?

Answer 3

Lengths that are the same.

Answer 5

For two polynomials to be congruent, you need two things:
1) corresponding sides must be congruent
2) corresponding angles must be congruent

Look at each pair of polynomials. If both of the conditions above are met, then the transformations are isometries.

It is not enough for just the pairs of corresponding sides to be congruent.
