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
Serjik [45]

Answer:

3 units.

Step-by-step explanation:

Given that the line segment AB has a length of 3 units.

Now, the line is translated 2 units to the right on a coordinate plane to obtain another line segment A'B'.

So, A'B' is the new line segment the length of which we have to find.

Since by translation both the points A and B both are sifted equally with respect to the coordinate axes so, the distance between A' and B' will remain the same as the distance between A and B i.e. 3 units. (Answer)
