Educational worksheet for identifying shapes based on the number of sides.

Let’s go step by step to name each shape based on how many sides it has.

We are told:
- Triangle → 3 sides
- Quadrilateral → 4 sides (this includes squares, rectangles, parallelograms, trapezoids, rhombuses — all have 4 sides)
- Pentagon → 5 sides
- Hexagon → 6 sides

Now let’s look at each shape one by one:

1. First shape (top left): It has 5 sides → Pentagon

2. Second shape (top right): It has 3 sides → Triangle

3. Third shape (second row, left): It has 4 sides → Quadrilateral
(It’s a trapezoid, but since the worksheet says “named by number of sides”, we use “quadrilateral”)

4. Fourth shape (second row, right): It has 6 sides → Hexagon

5. Fifth shape (third row, left): It has 3 sides → Triangle

6. Sixth shape (third row, right): It has 4 sides → Quadrilateral
(It’s a square, but again, we’re naming by side count)

7. Seventh shape (fourth row, left): It has 4 sides → Quadrilateral
(It’s a parallelogram)

8. Eighth shape (fourth row, right): It has 4 sides → Quadrilateral
(It’s a rhombus or diamond shape — still 4 sides)

9. Ninth shape (fifth row, left): It has 4 sides → Quadrilateral
(It’s a rectangle)

10. Tenth shape (fifth row, right): It has 5 sides → Pentagon

✔ All shapes checked and matched correctly by side count.
