Dear stuent

Please post one question at a time

ABCD is parallelogram
Draw traingle AA1C
AA1 + A1C = AC
A1 is mipoint of BC
A1C = 0.5 BC
AA1+ 0.5BC = AC
AA1 = AC -0.5BC ...........(1)

Draw traingle AB1C
AB1 + B1C = AC
B1C = 0.5DC
AB1 = AC - 0.5DC...........(2)
adding 1 and 2
AA1 +AB1 = 2AC -0.5(BC +AB)
But we know from traingular law of addition
AB + BC = AC
AA1 + AB1 = 2AC - 0.5AC
AA1 + AB1 = 1.5 AC
S0, lmbda = 1.5
