Color the quadrilaterals using the provided color key.

I'll help you solve this quadrilateral coloring worksheet step by step.

Step 1: Understanding the color key
- Rectangle = Blue
- Parallelogram = Purple
- Rhombus = Green
- Kite = Red
- Trapezoid = Yellow

Step 2: Identifying each shape

Let me go through the shapes row by row:

Row 1:
1. Square - This is a special rectangle (all angles are 90°) → Blue
2. Parallelogram (slanted, opposite sides parallel) → Purple
3. Diamond/rhombus shape (all sides equal, slanted) → Green
4. Rectangle (horizontal) → Blue

Row 2:
5. Parallelogram (tall, slanted) → Purple
6. Parallelogram (short, slanted) → Purple
7. Rhombus (diamond shape) → Green
8. Trapezoid (one pair of parallel sides) → Yellow

Row 3:
9. Rhombus (diamond shape) → Green
10. Square → Blue
11. Parallelogram (slanted) → Purple
12. Rhombus (diamond shape) → Green

Row 4:
13. Square → Blue
14. Parallelogram (tall, slanted) → Purple
15. Rectangle (horizontal) → Blue

Final Answer:

Here's how to color each shape:

Row 1 (left to right): Blue, Purple, Green, Blue

Row 2 (left to right): Purple, Purple, Green, Yellow

Row 3 (left to right): Green, Blue, Purple, Green

Row 4 (left to right): Blue, Purple, Blue
