Worked Example 1
Name the Quadrilateral
A quadrilateral has 4 equal sides but no right angles. What is it?
- 14 equal sides means it is a rhombus.
- 2It has no right angles, so it is not a square.
Answer: A rhombus

What Is Benchmark MA.3.GR.1.2?
A quadrilateral is a closed figure with 4 straight sides. Students identify and draw parallelograms, rhombuses (rhombi), rectangles, squares, and trapezoids based on their defining attributes, and tell them apart from non-examples.
Florida's B.E.S.T. glossary defines a trapezoid as a quadrilateral with at least one pair of parallel sides. A parallelogram has two pairs of parallel sides, a rhombus has 4 equal sides, a rectangle has 4 right angles, and a square has both.
Official benchmarkIdentify and draw quadrilaterals based on their defining attributes. Quadrilaterals include parallelograms, rhombi, rectangles, squares and trapezoids.

Worked Examples
Worked Example 2
Is a Square a Rhombus?
Is every square also a rhombus?
- 1A rhombus is a quadrilateral with 4 equal sides.
- 2A square has 4 equal sides (and also 4 right angles).
Answer: Yes, every square is a rhombus
Common Mistakes to Watch For
Thinking a square is not a rectangle
Wrong:A square can't be a rectangle because its sides are all the same length.
A rectangle needs 4 right angles. A square has 4 right angles, so it is a special rectangle.
Using a narrow definition of trapezoid
Wrong:A parallelogram can't be a trapezoid.
In Florida's B.E.S.T. glossary, a trapezoid has at least one pair of parallel sides. A parallelogram has two pairs, so it is also a trapezoid.
Helpful Math Tip
Draw shapes on grid paper and sort them into a chart. Ask your child to name every category each shape belongs to.
