Given:
There are four shapes square, parallelogram, isosceles trapezoid and rectangle.
To find:
The shape is the most general of the quadrilaterals.
Step-by-step explanation:
As we know,
If the quadrilateral has equal opposite sides and equal opposite angles, then it is a parallelogram.
So,
All squares are parallelograms.
All rectangles are parallelograms.
All rhombus is a parallelogram.
Therefore, the most general of the quadrilaterals is a parallelogram.
Final answer:
A parallelogram is the most general of the quadrilaterals.
