DEF is an equilateral triangle with sides of unit length 8. D'E'F'

Question

results from translating DEF
9 units down and 2 units to the left. What is the length of any one side of D'E'F'

Answer 1

The triangle DEF is an equilateral triangle with sides of unit length 8. When translating a shape, the lengths of the sides do not change; they simply move to a different location.

Thus, even after translating triangle DEF to form triangle D'E'F', the lengths of the sides remain the same. Therefore, the length of any one side of triangle D'E'F' is still \( 8 \) units.
