ddcamp · Answer

If AB=BC=CD=AD, then we know it has to be a rhombus.

Is angle B is 90°, then so must angle D. (opposite angles are congruent)
Angle A + Angle C = 180° (all angles add up to 360)
Angle A = Angle C (opposite angles are congruent
Angle A = Angle C = 90°
All angles are right angles, so it is a rectangle.

A square is the only shape that is a rectangle and a rhombus.
