2D Shape Attributes Chart Worksheets (SB11818) - SparkleBox - Free Printable

I'll solve this problem by identifying each 2D shape and filling in the table with its name, number of sides, and number of corners.

Let me start by examining each shape one by one.

First, let's look at the triangle:
- It's a three-sided polygon
- Name: Triangle
- Sides: 3
- Corners: 3

Next, the circle:
- It's a round shape with no straight edges
- Name: Circle
- Sides: 0 (or sometimes considered to have 1 curved side, but typically 0 for elementary education)
- Corners: 0

Then, the square:
- It's a four-sided polygon with equal sides and right angles
- Name: Square
- Sides: 4
- Corners: 4

Finally, the rectangle:
- It's a four-sided polygon with opposite sides equal and right angles
- Name: Rectangle
- Sides: 4
- Corners: 4

Now I'll fill in the table with this information.

The completed table would be:

| Shape | Name | How many sides? | How many corners? |
|-------|----------|-----------------|-------------------|
| △ | Triangle | 3 | 3 |
| ○ | Circle | 0 | 0 |
| □ | Square | 4 | 4 |
| ▭ | Rectangle| 4 | 4 |

This completes the task of identifying the 2D shapes and their attributes.
