Points a (-10,-6) and b (6,2) are the endpoints of ab. what are the coordinates of point c on ab such that ac is 3/4 the length of ab?
a. (0,-1)
b. (2,0)
c. (-2,-2)
d. (4,1)

In right ∆abc shown below, the midpoint of hypotenuse ac is located at d and segment bd is drawn.if ab = 12 and bc = 16, then explain why bd = 10. hint: consider what you know about the diagonals of a rectangle.
