Question

All squares are not parallelograms.

• A. True
• B. False

Answer 1

The correct option is B False

$\Rightarrow$ A parallelogram is a quadrilateral with opposite sides parallel and sum of its adjacent sides are supplementary.

$\Rightarrow$ In square opposite sides are parallel and measure of each angle is ${90}^o$, so sum of its adjacent also supplementary.

$\Rightarrow$ So, square contains all the properties of a parallelogram.

$\therefore$ All squares are parallelogram.

So, given statement is false.
