- Every square is a rhombus. (1 point)
- Every rectangle has 4 equal sides. (1 point)
Question 3 – Two mystery shapes [2 pts]
- I have 4 equal sides and no right angles. Name me. (1 point)
- I have 4 right angles and 2 pairs of equal sides, but my sides are not all equal. Name me. (1 point)
Question 4 – Sort the shapes [3 pts]
| Shape | Is it a rectangle? | Is it a rhombus? |
|---|---|---|
| Square | ? | ? |
| A 7 by 3 rectangle | ? | ? |

Question 5 – Draw a new quadrilateral [2 pts]
Draw a quadrilateral that is not a rhombus, not a rectangle, and not a square. Label the sides with lengths that show why.
Question 6 – Equal parts on a grid [2 pts]
The rectangle is made of 18 equal squares. Draw lines to cut it into 3 parts with equal area. What fraction of the rectangle is one part?
Question 7 – The cut square [2 pts]
A square napkin with sides of \(8 ext{ in}\) is cut by a straight line from one corner to the middle of the opposite side. Aisha says the shaded triangle is \(\frac{1}{2}\) of the square because there are 2 parts. Is she right? Explain.
Question 8 – Corn bread tray [3 pts]
Ethan bakes a rectangular tray of corn bread and cuts it into 8 pieces with equal area.
- What fraction of the tray is one piece? (1 point)
- Ethan cuts a second tray of the same size into 4 pieces with equal area. Are those pieces bigger or smaller than the first ones? (1 point)
- Explain your answer to part b. (1 point)
Question 9 – Two cuts [2 pts]
A square is cut into 4 parts with equal area. Maya cuts hers into 4 small squares. Jamal cuts his into 4 triangles. Do both children have fourths? Explain.
Key facts behind this quadrilaterals test
- A quadrilateral has exactly 4 straight sides and 4 corners.
- A rhombus has 4 equal sides; a rectangle has 4 right angles.
- A square is a rhombus and a rectangle at the same time.
- Some quadrilaterals are not rhombuses, rectangles, or squares.
- Equal parts have equal area, and each of n equal parts is 1/n of the whole.
