In the figure, $ABCD$ and $AEFD$ are two parallelograms. Prove that $PE = FQ$.
"
Given:
$ABCD$ and $AEFD$ are two parallelograms.
To do:
We have to prove that $PE = FQ$.
Solution:
In $\triangle AEP$ and $\triangle DFQ$,
$AE = DF$ (Opposite sides of a parallelogram)
$\angle AEP = \angle DFQ$ (Corresponding angles)
$\angle APE = \angle DQF$ (Corresponding angles)
Therefore, by AAS axiom,
$\triangle AEP \cong \triangle DFQ$
This implies,
$PE = QF$ (CPCT)
Hence proved.
