Question

Line segment AB has a length of 3 units. It is translated 2 units to the right on a coordinate plane to obtain line segment A′B′. What is the length of A′B′?

1 unit
2 units
3 units
5 units

Answer 1

A translation is a movement of a point or line to another spot on a plane. A translation of a line only moves the line, and nothing else. The length doesn't change.

The length of A'B' is 3 units.

Answer 2

A translation only moves a line, line-segment, or shape, and does not affect the measurement in any way. the length will still stay the same for Line segment AB.

So your answer is 3 units
