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

Which quadrilaterals have 4 sides of equal length?

Which quadrilaterals have 4 right angles?

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

So, ________ are in both circles.
What type of quadrilateral is in both circles?
Squares , Rhombus and Rectangle

What do I need to find?
The section where the circles overlap are both rectangles and rhombuses.

What information am I given?
Squares , Rhombus and Rectangle are the quadrilaterals
The circles labeled Rectangles and Rhombuses

Plan

What is my plan or strategy?
Squares , Rhombus and Rectangle are the quadrilaterals

Solve

All quadrilaterals have the four corners and four sides

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

Which quadrilaterals have 4 sides of equal length?
Squares have 4 sides of equal length.

Which quadrilaterals have 4 right angles?
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.
