A) \[\angle P={{100}^{o}},\,\,\angle Q={{80}^{o}},\,\,\angle R={{100}^{o}}\]
B) \[\angle P={{85}^{o}},\,\,\angle Q={{85}^{o}},\,\,\angle R={{95}^{o}}\]
C) \[PQ=7\,\,cm,\,\,QR=7\,\,cm,\,\,RS=8\,\,cm,\]\[OS=5.2\,\,cm\]
D) \[OP=6.5\,\,cm,\,\,OQ=6.5\,\,cm,\,\,OR=5.2\,\,cm,\] \[OS=5.2\,\,cm\]
Correct Answer: A
Solution :
\[\Rightarrow \]\[\angle P=\angle R={{100}^{o}}\]and \[\angle Q=\angle S={{80}^{o}}\] Adjacent sides of a parallelogram are not equal and sum of the adjacent angles is supplementary.You need to login to perform this action.
