Polygon abcd is plotted on a coordinate plane. if the polygon translates 3 units to the left and 1 unit down, the length of diagonal a’c’ is __ units ( 2,3or 6) if the polygon translates 3 units further to the left and four units down, the length of diagonal a’c’ ( increases, decreases or remains the same

here, the entire polygon is translated towards left and down.

this will not affect the length of the sides and diagonals of the polygon.

at present, the length of the diagonal is 2 units.

consider the first translation.

here, every point is translated 3 units to the left and 1 unit down. so, a' will be (0, 3) and c' will be (0, 1).

note that a'c' = 2 which is its original length.

hence, as translation will not affect the length of the diagonal, length of the diagonal = 2 units always.
