Question

state and prove mid piont theorem.
issme <1 =<2 kese aya...
please help me....
a big confusion

Answer 1

The line joining the mid points of the 2 sides of the triangle is parallel as well as half of the third side

Answer 2

<1= <2 ( vertically opposite angle)
by SAS
∆AQP=~ ∆ RQC
THEREFORE, PQ = RQ BY CPCT
AND ALSO, <A = <C. BY CPCT
AP = RC
These are alternate interior angle. so that, AB // RC AND AP = RC
SO THAT RC = PB (AP=PB)
SO, PBCR IS A //GM
PQ//BC
BC = PQ +QR
BC= 2 PQ (PQ=QR)
PQ = 1/2 BC....
HENCE PROVED....
