A) \[a=2,\,b=4\]
B) \[a=3,\,b=4\]
C) \[a=2,\,b=3\]
D) \[a=3,\,b=5\]
Correct Answer: C
Solution :
[c] Daygrm |
Mid-point of \[PR=\left( \frac{1+5}{2},\frac{2+7}{2} \right)=\left( 3,\frac{9}{2} \right)\] |
Mid-points of \[SQ=\left( \frac{4+a}{2},\frac{6+b}{2} \right)\] |
Diagonals of parallelogram bisect each other. |
\[\therefore \,\,\,\,\,\,\,\,\,\,\left( 3,\frac{9}{2} \right)=\left( \frac{4+a}{2},\frac{6+b}{2} \right)\] |
\[\Rightarrow \,\,\,\,\,\,\,\,\,\,3=\frac{4+a}{2},\,\,\frac{9}{2}=\frac{6+b}{2}\] |
\[\Rightarrow \,\,\,\,\,\,\,\,\,\,a=2,\,\,\,b=3.\] |
