Question

Line segment AB has a length of 5 units. It is translated 3 units to the right on a coordinate plane to obtain line segment A’B’. What is the length of A’B’?

A: 2 units
B: 3 units
C: 4 units
D: 5 units

Answer 1

D) 5units

Explanation:

I took the test

Answer 2

Option D: 5 units

Explanation:

we know that

We have a two categories of transformation

A rigid transformations that do not change the shape or size of the preimage and non-rigid transformations that change the size but not the shape of the preimage

The translation is a rigid transformation

so

The size of the preimage and the size of the image are equal

therefore

AB=A'B'

The length of A'B' is 5 units
