Let’s solve this step by step.
We have a Venn diagram with two circles:
- Left circle: “Red shapes”
- Right circle: “Shapes with 4 sides”
- Middle overlapping part: “Both” — meaning shapes that are BOTH red AND have 4 sides
Below the diagram, there are 10 shapes in boxes. We need to sort them into the correct place in the Venn diagram.
First, let’s list all the shapes and check each one:
Top row (left to right):
1. Red star → It is red, but has 5 sides → So it goes in “Red shapes” only.
2. Green trapezoid → Not red, but has 4 sides → Goes in “Shapes with 4 sides” only.
3. Red diamond (rhombus) → Red AND has 4 sides → Goes in “Both”.
4. Blue rectangle → Not red, but has 4 sides → Goes in “Shapes with 4 sides” only.
5. Red circle → Red, but has 0 straight sides (not 4) → Goes in “Red shapes” only.
Bottom row (left to right):
6. Yellow trapezoid → Not red, but has 4 sides → Goes in “Shapes with 4 sides” only.
7. Red pentagon → Red, but has 5 sides → Goes in “Red shapes” only.
8. Red triangle → Red, but has 3 sides → Goes in “Red shapes” only.
9. Red parallelogram → Red AND has 4 sides → Goes in “Both”.
10. Red square → Red AND has 4 sides → Goes in “Both”.
Now let’s group them:
✔ Red shapes ONLY (red but NOT 4 sides):
- Red star (5 sides)
- Red circle (no straight sides)
- Red pentagon (5 sides)
- Red triangle (3 sides)
✔ Shapes with 4 sides ONLY (NOT red, but 4 sides):
- Green trapezoid
- Blue rectangle
- Yellow trapezoid
✔ Both (red AND 4 sides):
- Red diamond
- Red parallelogram
- Red square
Wait — let’s double-check the red parallelogram and red square. Yes, both are red and have 4 sides. Good.
Also, note: The green trapezoid, blue rectangle, and yellow trapezoid are not red, so they go only in the right circle.
The red star, red circle, red pentagon, and red triangle are red but don’t have 4 sides, so they go only in the left circle.
Final grouping:
Left Circle (Red shapes only):
→ Red star, Red circle, Red pentagon, Red triangle
Right Circle (Shapes with 4 sides only):
→ Green trapezoid, Blue rectangle, Yellow trapezoid
Middle (Both):
→ Red diamond, Red parallelogram, Red square
That’s all 10 shapes sorted correctly.
Final Answer:
- Red shapes only: red star, red circle, red pentagon, red triangle
- Shapes with 4 sides only: green trapezoid, blue rectangle, yellow trapezoid
- Both (red and 4 sides): red diamond, red parallelogram, red square
