Step-by-step explanation:

The complete question is

If a translation takes triangle CAT to C'A'T', what is A'T'?

Triangle CAT is shown. C is at 0, 0, A is at negative 2, 1, T is at negative 1, 4

we know that

A translation is a rigid transformation that produce congruent figures

If two figures are congruent, then its corresponding sides and its corresponding angles are congruent

In this problem

triangle CAT and triangle C'A'T' are congruent

so

CA≅C'A'

AT≅A'T'

CT≅C'T'

Find the distance AT

In this problem we have

A(-2,1) and T(-1,4)

the formula to calculate the distance between two points is equal to

substitute
