Students sort geometric shapes into categories based on the number of right angles they contain.

Okay, now I see the bottom row of shapes. On the left is a cloud shape with only curved lines, so it has no angles at all and belongs in the "No right angles" category. In the middle is an L-shaped polygon. I can clearly see three corners that are 90-degree angles, so this shape goes into the "2 or more right angles" column. On the right is another right-angled triangle, which has one 90-degree corner, placing it in the "1 right angle" category. I have now examined all the shapes and am ready to sort them into the correct columns.

Based on my analysis of each shape, here is the solution for the "Right angles sorting activity":

No right angles:
- Circle
- Six-pointed star
- Cloud

1 right angle:
- Right-angled triangle (top row)
- Right-angled triangle (middle row)
- Right-angled triangle (bottom row)

2 or more right angles:
- Rectangle
- Square
- L-shaped polygon
