Sort shapes worksheet with objects to categorize into circles, triangles, and rectangles.

Problem Description:

The task is to sort shapes into the correct categories: circles, triangles, and rectangles. The image provided shows a worksheet with three columns labeled for each shape type, along with several images at the bottom that need to be sorted.

Solution Approach:

1. Identify the Shapes in Each Category:
- Circles: Round shapes with no edges or corners.
- Triangles: Three-sided polygons with straight edges.
- Rectangles: Four-sided polygons with opposite sides equal and all angles at 90 degrees.

2. Analyze Each Image:
- Carefully examine each image at the bottom of the worksheet and determine which category it belongs to based on its geometric properties.

3. Sort the Images:
- Place each image into the appropriate column (circle, triangle, or rectangle).

Step-by-Step Analysis of Each Image:

#### Bottom Row Images:
1. Soccer Ball:
- Shape: Round (sphere-like, but treated as a circle for this context).
- Category: Circles.

2. Pizza Slice:
- Shape: Triangular (three straight edges).
- Category: Triangles.

3. Cookie:
- Shape: Round (circular).
- Category: Circles.

4. Book:
- Shape: Rectangular (four straight edges with opposite sides equal).
- Category: Rectangles.

5. Flag Pole:
- Shape: Not a closed shape; it has a triangular flag.
- Category: Triangles (focus on the flag part).

6. House:
- Shape: Combination of a triangle (roof) and rectangles (walls).
- Category: Triangles (mainly due to the roof).

7. Sun:
- Shape: Circular (round).
- Category: Circles.

8. Pie Slice:
- Shape: Triangular (three straight edges).
- Category: Triangles.

9. Pizza Slice (again):
- Shape: Triangular (three straight edges).
- Category: Triangles.

Final Sorting:

- Circles Column: Soccer Ball, Cookie, Sun.
- Triangles Column: Pizza Slice, Flag Pole, House, Pie Slice, Pizza Slice (again).
- Rectangles Column: Book.

Final Answer:

\[
