triangle XYZ is translated down 4 units to the left 8 units. The length of side XY is 10 units. What is the length of side X’Y’?
To find the length of side X'Y', we need to know the direction and distance of the translation.
The triangle is translated "down 4 units to the left 8 units."
This means that X' is 8 units to the left of X and 4 units below Y.
Since the triangle is translated to the left, the length of side X'Y' remains the same as the length of side XY, which is 10 units.
Therefore, the length of side X'Y' is 10 units.
