**Solve**

What is true about all quadrilaterals?

Answer:

All quadrilaterals have the four corners and four sides

Which quadrilaterals have 2 pairs of opposite sides that are parallel?

Answer:

Squares and rectangles have 2 pairs of opposite sides that are parallel

Which quadrilaterals have 4 sides of equal length?

Answer:

Squares have 4 sides of equal length.

Which quadrilaterals have 4 right angles?

Answer:

Squares and rectangles have 4 right angles

The quadrilaterals in the section where the circles overlap have 2 pairs of opposite sides that are parallel, 4 sides of equal length, and 4 right angles.

So, Squares are in both circles.
