Triangle XY Z is translated down 4 units and to the left 8 units. The length of side XY is 10 units. What is the length of side X'Y'? (1 point)
To find the length of side X'Y', we need to first understand that translation does not affect the lengths of the sides of the triangle, only its position in space.
Since side XY is 10 units long, side X'Y' will also be 10 units long.
Therefore, the length of side X'Y' is 10 units.
