Classifying Quadrilaterals worksheet with shapes and multiple-choice options.

Let’s go through each quadrilateral one by one and figure out what it is. We’ll use simple rules:

- A square has 4 equal sides and 4 right angles (like a perfect box).
- A rectangle has opposite sides equal and 4 right angles (like a stretched square).
- A rhombus has 4 equal sides, but angles are not necessarily right angles (like a diamond shape).
- A parallelogram has two pairs of parallel sides — opposite sides are equal and parallel.
- A trapezoid has only ONE pair of parallel sides (the other two sides are slanted or different).

Now let’s look at each shape in order (left to right, top to bottom):

---

Row 1:

1. First shape: Looks like a tilted square with all sides equal and right angles → Square
Also fits: Rhombus, Parallelogram, Quadrilateral

2. Second shape: Smiling face inside a rectangle → has 4 right angles, opposite sides equal → Rectangle
Also fits: Parallelogram, Quadrilateral

3. Third shape: Plain four-sided figure with no right angles, but both pairs of opposite sides look parallel → Parallelogram
Also fits: Quadrilateral

---

Row 2:

4. Fourth shape: Rectangle again? Wait — actually, this looks like a rectangle too → Rectangle
Also fits: Parallelogram, Quadrilateral

5. Fifth shape: Diamond-shaped, all sides equal, no right angles → Rhombus
Also fits: Parallelogram, Quadrilateral

6. Sixth shape: Very skinny parallelogram → still two pairs of parallel sides → Parallelogram
Also fits: Quadrilateral

---

Row 3:

7. Seventh shape: Only one pair of parallel sides (top and bottom), sides slant inward → Trapezoid
Also fits: Quadrilateral

8. Eighth shape: Looks like a rhombus or maybe a square? But angles aren’t right — so Rhombus
Also fits: Parallelogram, Quadrilateral

9. Ninth shape: Smiling trapezoid — only one pair of parallel sides → Trapezoid
Also fits: Quadrilateral

---

Row 4:

10. Tenth shape: Flat parallelogram → Parallelogram
Also fits: Quadrilateral

11. Eleventh shape: Perfect square → Square
Also fits: Rhombus, Rectangle, Parallelogram, Quadrilateral

12. Twelfth shape: Smiling square → Square
Also fits: Rhombus, Rectangle, Parallelogram, Quadrilateral

---

Now, for each shape, we circle ALL that apply from the list: Quadrilateral, Rhombus, Square, Parallelogram, Trapezoid, Rectangle.

Remember: All squares are also rectangles, rhombuses, parallelograms, and quadrilaterals.
All rectangles are parallelograms and quadrilaterals.
All rhombuses are parallelograms and quadrilaterals.
All parallelograms are quadrilaterals.
Trapezoids are just quadrilaterals with one pair of parallel sides.

So here’s the final answer for each shape (in order):

1. Square → Circle: Quadrilateral, Rhombus, Square, Parallelogram
2. Rectangle → Circle: Quadrilateral, Parallelogram, Rectangle
3. Parallelogram → Circle: Quadrilateral, Parallelogram
4. Rectangle → Circle: Quadrilateral, Parallelogram, Rectangle
5. Rhombus → Circle: Quadrilateral, Rhombus, Parallelogram
6. Parallelogram → Circle: Quadrilateral, Parallelogram
7. Trapezoid → Circle: Quadrilateral, Trapezoid
8. Rhombus → Circle: Quadrilateral, Rhombus, Parallelogram
9. Trapezoid → Circle: Quadrilateral, Trapezoid
10. Parallelogram → Circle: Quadrilateral, Parallelogram
11. Square → Circle: Quadrilateral, Rhombus, Square, Parallelogram, Rectangle
12. Square → Circle: Quadrilateral, Rhombus, Square, Parallelogram, Rectangle

Final Answer:
For each shape, circle these terms:

1. Quadrilateral, Rhombus, Square, Parallelogram
2. Quadrilateral, Parallelogram, Rectangle
3. Quadrilateral, Parallelogram
4. Quadrilateral, Parallelogram, Rectangle
5. Quadrilateral, Rhombus, Parallelogram
6. Quadrilateral, Parallelogram
7. Quadrilateral, Trapezoid
8. Quadrilateral, Rhombus, Parallelogram
9. Quadrilateral, Trapezoid
10. Quadrilateral, Parallelogram
11. Quadrilateral, Rhombus, Square, Parallelogram, Rectangle
12. Quadrilateral, Rhombus, Square, Parallelogram, Rectangle
