Four points have the following coordinates: a(-2,-6) b(-5,-2) c(3,4) d(6,0). you may find it to sketch, plot, or graph the 4 points and label the coordinates. a sketch is fine. desmos is fine. the figure abcd is either a parallelogram, rhombus, rectangle, or square. determine which one:

1.for each of the four segments compute the slopes and show all your work. give slopes as fractions reduced to lowest terms. be sure to indicate downward slopes as negative.

2.what do you know about the angles at the 4 points? justify your answer using your calculations from part “a”.

3.compute the lengths of all four sides. show all your work. determine the shape of abcd and justify your answer.
