Identify cones and pyramids worksheet with shapes to color based on geometric properties.

Let's solve the problem step by step.

---

Task:

Identify cones and pyramids.
- Shade cones in red.
- Shade pyramids in blue.

---

Step 1: Understand the Definitions

#### 🔹 Cone:
- A cone has:
- One circular base.
- A curved surface that tapers to a single point (the apex).
- Example: Ice cream cone, traffic cone.

#### 🔹 Pyramid:
- A pyramid has:
- A polygonal base (e.g., triangle, square, rectangle).
- Flat triangular faces that meet at a common vertex (apex).
- The shape of the base determines the name (e.g., triangular pyramid, square pyramid).

Step 2: Analyze Each Shape

We'll go through each shape one by one and classify it.

---

#### Row 1:
1. Cube → ✘ Not a cone or pyramid (it’s a prism).
2. Cylinder → ✘ Not a cone or pyramid (has two circular bases).
3. Cone → ✔ CONE → Shade RED
4. Rectangular prism → ✘ Not a cone or pyramid.

---

#### Row 2:
5. Triangular prism → ✘ Not a cone or pyramid.
6. Square pyramid → ✔ PYRAMID → Shade BLUE
7. Sphere → ✘ Not a cone or pyramid.
8. Triangle-shaped object? → Wait — this is actually a triangular pyramid (tetrahedron) → ✔ PYRAMID → Shade BLUE

Wait — let's double-check:

Actually, looking at the image:
- The 7th shape is a sphere → not relevant.
- The 8th shape is a triangular pyramid (tetrahedron) → ✔ PYRAMID → BLUE

---

#### Row 3:
9. Cone (lying on side) → This is still a cone (circular base, curved surface, pointed tip) → ✔ CONE → RED
10. Rectangular prism → ✘ Not a cone or pyramid.
11. Triangular pyramid (tetrahedron) → ✔ PYRAMID → BLUE

---

#### Row 4:
12. Cylinder (lying on side) → ✘ Not a cone or pyramid.
13. Square pyramid → ✔ PYRAMID → BLUE
14. Rectangular prism → ✘ Not a cone or pyramid.
15. Cone (side view) → ✔ CONE → RED

Summary of Shapes to Color:

| Shape | Type | Color |
|------|------|-------|
| 3rd in Row 1 | Cone | 🔴 Red |
| 6th in Row 2 | Square Pyramid | 🔵 Blue |
| 8th in Row 2 | Triangular Pyramid | 🔵 Blue |
| 9th in Row 3 | Cone | 🔴 Red |
| 11th in Row 3 | Triangular Pyramid | 🔵 Blue |
| 13th in Row 4 | Square Pyramid | 🔵 Blue |
| 15th in Row 4 | Cone | 🔴 Red |

✔ Final Answer:

- Shade red (cones):
- Top row, third shape (upright cone)
- Third row, first shape (cone on its side)
- Bottom row, last shape (cone on its side)

- Shade blue (pyramids):
- Second row, middle shape (square pyramid)
- Second row, rightmost shape (triangular pyramid)
- Third row, rightmost shape (triangular pyramid)
- Fourth row, second shape (square pyramid)

🎯 Notes:

- Cylinders, cubes, prisms, and spheres are not cones or pyramids.
- Even if a cone is tilted or lying down, it's still a cone.
- Pyramids have flat faces and a polygonal base; they taper to a point.

✔ Solution Complete!

Now you can shade the correct shapes accordingly.
