Question

Given triangle ABC, A(-5,2), B(7,4), C(3,-9). If D(1,3), determine if segment CD is an altitude, median, perpendicular bisector, or angle bisector. Show work to support your answer.

Answer 1

Graph the points first on a two-dimensional plane.

Answer 2

To find the midpoint, add the x values and divide by 2, then add the y values and divide by 2. A is (-5,2) and B is (7,4) (-5+7)/2=1 and (2+4)/2 = 3 So (1,3) is the midpoint and point D is (1,3) So CD must be a median.
