Question

• How do you use the distance formula and slope formula to classify a quadrilateral?

Answer 1

use 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
