If a translation takes triangle CAT to C′A′T′, what is A′T′?

Question

triangle CAT with vertex A at negative 2 comma 1, vertex T at negative 1 comma 4 and vertex C at 0 comma 0, side AT has a measure of square root of 10 units, side TC has a measure of square root of 17 units, and side AC has a measure of square root of 5 units

square root of 10
4
5
Cannot be determined

Answer 1

Cannot be determined

Since the translation only tells us how the triangle is moved to C'A'T', we do not have enough information to determine the length of A'T'.
