Rectangle ABCD is translated 6 units to the right and 1 unit down to form rectangle A′B′C′D′ . Diagonal BD measures 6 units in length. What is the length of diagonal B′D′ ?(1 point)
The length of diagonal BD is 6 units. Translating the rectangle 6 units to the right and 1 unit down does not change the length of any of its sides or diagonals. Therefore, the length of diagonal B'D' is also 6 units.
