Classifying quadrilaterals worksheet for Grade 4 students.

Let’s go step by step to classify each quadrilateral.

We are given 9 shapes, and we need to label each one as:
- square
- rectangle
- rhombus
- parallelogram
- trapezoid

First, let’s remember what each shape means (in simple terms):

✔ Trapezoid – has exactly ONE pair of parallel sides.
✔ Parallelogram – has TWO pairs of parallel sides. Opposite sides are equal and parallel.
✔ Rectangle – a parallelogram with four right angles (all corners are 90°).
✔ Rhombus – a parallelogram with all four sides equal in length.
✔ Square – a special rectangle AND rhombus — all sides equal AND all angles 90°.

Now let’s look at each shape:

---

Shape 1: Looks like a slanted four-sided figure. Both pairs of opposite sides are parallel → it’s a parallelogram. Not a rectangle or rhombus because angles aren’t 90° and sides don’t look equal.

→ Answer: Parallelogram

---

Shape 2: Has only one pair of parallel sides (top and bottom), the other two sides slope inward → this is a trapezoid.

→ Answer: Trapezoid

---

Shape 3: Slanted again, both pairs of opposite sides parallel → parallelogram. Sides don’t look equal, angles not 90° → not rhombus or rectangle.

→ Answer: Parallelogram

---

Shape 4: Four right angles, opposite sides equal → this is a rectangle. All angles 90°, but sides not all equal → not a square.

→ Answer: Rectangle

---

Shape 5: Four right angles, and all sides look equal → this is a square. (A square is also a rectangle and a rhombus, but “square” is the most specific name.)

→ Answer: Square

---

Shape 6: Only one pair of parallel sides (top and bottom) → trapezoid.

→ Answer: Trapezoid

---

Shape 7: Four right angles, opposite sides equal → rectangle. Again, not all sides equal → not a square.

→ Answer: Rectangle

---

Shape 8: Four right angles, all sides equal → square.

→ Answer: Square

---

Shape 9: One pair of parallel sides (top and bottom) → trapezoid.

→ Answer: Trapezoid

---

Final Answer:
1. Parallelogram
2. Trapezoid
3. Parallelogram
4. Rectangle
5. Square
6. Trapezoid
7. Rectangle
8. Square
9. Trapezoid
