Triangle XYZ 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) units

Answer 1

When a triangle undergoes a translation, the lengths of its sides remain unchanged. This means that the translation does not affect the dimensions of the triangle.

Since the length of side XY is 10 units, the length of side X′Y′, which corresponds to side XY after translation, will also be 10 units.

Thus, the length of side X′Y′ is \( \boxed{10} \) units.
