each side.
- Determine the slope of each side of the quadrilateral whose vertices are A(5,6), B(13,6),
C(11,2). Can you tell what kind of quadrilateral it is? - A quadrilateral has as vertices the points M(a,b), N(c,d), Q(c+d,e), P(a+d,e). Find the slope
of each side. - C is the mid-point of AB, A if the point (-3,-2), and B is the point (2,8).
