Grade 5 Geometry Worksheets: Quadrilaterals | Worsheets library - Free Printable

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

We’re given these categories:
square, rectangle, rhombus, parallelogram, trapezoid, scalene

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

- Square: All 4 sides equal, all angles 90° → looks like a perfect box with equal sides.
- Rectangle: Opposite sides equal, all angles 90° → like a stretched square.
- Rhombus: All 4 sides equal, but angles don’t have to be 90° → like a diamond shape.
- Parallelogram: Opposite sides are parallel and equal — can be slanted.
- Trapezoid: Only one pair of opposite sides is parallel.
- Scalene: No sides equal, no parallel sides — completely irregular.

Now, look at each shape:

1. Shape 1: Slanted, opposite sides look equal and parallel → parallelogram
2. Shape 2: Perfect square — all sides equal, right angles → square
3. Shape 3: Rectangle — opposite sides equal, right angles, but not all sides equal → rectangle
4. Shape 4: Irregular — no sides equal, no parallel sides → scalene
5. Shape 5: Slanted, opposite sides equal and parallel → parallelogram
6. Shape 6: One pair of parallel sides (top and bottom), non-parallel sides slant inward → trapezoid
7. Shape 7: Same as #1 and #5 — slanted parallelogram → parallelogram
8. Shape 8: Same as #3 — rectangle → rectangle
9. Shape 9: Same as #1, #5, #7 → parallelogram

Double-checking:
- Squares are also rectangles and rhombuses, but since “square” is listed separately, we use the most specific term.
- Rhombus isn’t used here because none of the shapes have all sides equal except #2 (which is a square).
- Trapezoid only appears in #6.
- Scalene only in #4.

All classifications match the visual properties.

Final Answer:
1. parallelogram
2. square
3. rectangle
4. scalene
5. parallelogram
6. trapezoid
7. parallelogram
8. rectangle
9. parallelogram
