Prove that segments AD and AB are congruent and parallel
Prove that opposite sides are congruent and that the slopes of consecutive sides are equal
Prove that segments BC and CD are congruent and parallel
Prove that opposite sides are congruent and that the slopes of consecutive sides are opposite reciprocals

Prove that all sides are congruent and that the slopes of consecutive sides are opposite reciprocals.

Step-by-step explanation:

In order to two segmets to be perpendicular, the slope of both lines must be opposite and reciprocals, having a 90° interception and forming a square.
