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

To classify the quadrilaterals in the provided worksheet, we need to identify each shape based on its properties. Here's a step-by-step explanation for each figure:

Step 1: Understand the Properties of Each Quadrilateral

1. Square: All sides are equal, and all angles are 90°.
2. Rectangle: Opposite sides are equal, and all angles are 90°.
3. Rhombus: All sides are equal, but angles can vary (not necessarily 90°).
4. Parallelogram: Opposite sides are parallel and equal, but angles can vary.
5. Trapezoid: One pair of opposite sides is parallel.
6. Scalene (Irregular): No sides or angles are equal.

Step 2: Analyze Each Figure

#### Figure 1
- The shape has two pairs of parallel sides, but the sides are not equal.
- Classification: Parallelogram

#### Figure 2
- The shape has four equal sides and four right angles.
- Classification: Square

#### Figure 3
- The shape has opposite sides that are equal and parallel, and all angles are 90°.
- Classification: Rectangle

#### Figure 4
- The shape has one pair of parallel sides.
- Classification: Trapezoid

#### Figure 5
- The shape has two pairs of parallel sides, but the sides are not equal.
- Classification: Parallelogram

#### Figure 6
- The shape has one pair of parallel sides.
- Classification: Trapezoid

#### Figure 7
- The shape has two pairs of parallel sides, but the sides are not equal.
- Classification: Parallelogram

#### Figure 8
- The shape has opposite sides that are equal and parallel, and all angles are 90°.
- Classification: Rectangle

#### Figure 9
- The shape has two pairs of parallel sides, but the sides are not equal.
- Classification: Parallelogram
