The equation of line AG is y=_b_x. The midpoint of
 B(2a, 2b)
 BC is (a + c, b). Does the midpoint of BC lie on Ac?
 Why or why not?
 no, because bb does not equal a + c
 E(a, b)
 Fla + c, b)
 no, because
 (a + c) does not equal b
 G
 yes, because_b_b= a + c
 A(0,0)
 Dlc,0)
 C(20, 0)'
 yes, because ( 6 (a + c) = b
