For quadrilateral abcd, determine the most precise name for it. a(-2,3), b (9,3), c(5,6) and d(2,6). show your work and explain.

For this case, the first thing to do is to graph the ordered pairs given in the problem.
 Then, join the points to see the quadrilateral formed.
 In this case the quadrilateral is a trapezoid.
 The trapezoid is a geometric figure with four sides, of which only two are parallel.
