That is, each diagonal cuts the other into two equal parts, and the angle where they cross is always 90 degrees. Which diagonals bisect opposite angles Prove theorem -- If a parallelogram is a rhombus, each diagonal bisects a pair of opposite angles AD = BC (Opposite sides of a square are equal.) BD = BD (Common) AB = DC (Opposite sides of a square are equal.) Thus, By Corresponding parts of congruent triangles property we have: ∠ABD = ∠CBD. ∠ADB = ∠CDB. Therefore, in a square the diagonals bisect the opposite angles. Hence the correct choice is (d)
