Question

How can you use distance and slope formulas to classify quadrilaterals?

Answer 1

If the four pairs of intersecting lines have opposite reciprocal slopes, they have 90 degree angles. If the distance of all the sides are the same, it’s a square.

Answer 2

Sse the distance formula to find the length of the sides... opposite sides equal it could be a rectangle or parallelogram all sides equal, square or rhombus adjacent equal, kite and then the slope is used to check angles if the product of the 2 lines in -1 the lines are perpendicular (right angle) the the slopes of 2 lines are the same the sides are parallel. hope it helps.
