Let’s go step by step to match each 2D shape on the left with the correct 3D shape on the right.
We’re looking for which 3D shape has a face (a flat side) that matches the 2D shape.
---
Step 1: Triangle (top left)
→ Look at the 3D shapes. The triangular prism (second from top on right) has triangle faces.
✔ Match: Triangle → Triangular Prism
---
Step 2: Pentagon (second from top left)
→ A pentagon has 5 sides. Look for a 3D shape with a pentagonal face.
→ The pentagonal prism (fourth from top on right) has pentagons as its bases.
✔ Match: Pentagon → Pentagonal Prism
---
Step 3: Trapezoid (third from top left)
→ A trapezoid is a 4-sided shape with one pair of parallel sides.
→ Look at the 3D shapes — the trapezoidal prism (fifth from top on right) has trapezoids as its bases.
✔ Match: Trapezoid → Trapezoidal Prism
---
Step 4: Square (fourth from top left)
→ A square has 4 equal sides and 4 right angles.
→ The cube (top right) has all square faces.
✔ Match: Square → Cube
---
Step 5: Hexagon (fifth from top left)
→ A hexagon has 6 sides.
→ The hexagonal prism (third from top on right) has hexagons as its bases.
✔ Match: Hexagon → Hexagonal Prism
---
Step 6: Circle (bottom left)
→ A circle is round with no corners.
→ The cylinder (bottom right) has circular bases.
✔ Match: Circle → Cylinder
---
Now let’s list all the correct matches clearly:
- Triangle → Triangular Prism
- Pentagon → Pentagonal Prism
- Trapezoid → Trapezoidal Prism
- Square → Cube
- Hexagon → Hexagonal Prism
- Circle → Cylinder
These are the same matches shown in red arrows on the answer sheet.
Final Answer:
Triangle → Triangular Prism
Pentagon → Pentagonal Prism
Trapezoid → Trapezoidal Prism
Square → Cube
Hexagon → Hexagonal Prism
Circle → Cylinder
