Problem Description:
The task involves drawing small circles around each vertex (corner) of the given 3-dimensional shapes. The goal is to identify and mark all the vertices of each shape with small circles.
Solution Explanation:
#### Step 1: Understand the Task
- A
vertex in a 3D shape is a point where edges meet.
- The task requires identifying all vertices in each shape and marking them with small circles.
#### Step 2: Analyze Each Shape
We will go through each shape one by one and identify its vertices.
---
##### Shape 1: Rectangular Prism
- A rectangular prism has
8 vertices.
- Mark a small circle at each of the 8 corners of the prism.
---
##### Shape 2: Cube
- A cube also has
8 vertices.
- Mark a small circle at each of the 8 corners of the cube.
---
##### Shape 3: Triangular Pyramid (Tetrahedron)
- A triangular pyramid has
4 vertices.
- Mark a small circle at each of the 4 corners of the tetrahedron.
---
##### Shape 4: Cylinder
- A cylinder has
0 vertices because it does not have any sharp corners. It has curved surfaces and circular bases.
- Do not mark any circles for this shape.
---
##### Shape 5: Cone
- A cone has
1 vertex at its tip.
- Mark a small circle at the tip of the cone.
---
##### Shape 6: Sphere
- A sphere has
0 vertices because it is a perfectly round object with no corners or edges.
- Do not mark any circles for this shape.
---
##### Shape 7: Triangular Prism
- A triangular prism has
6 vertices.
- Mark a small circle at each of the 6 corners of the triangular prism.
---
#### Step 3: Draw the Circles
For each shape, carefully draw a small circle at every identified vertex. Ensure that the circles are clearly visible and placed accurately at the corners.

Final Answer:
Mark the vertices as follows:
1.
Rectangular Prism: 8 vertices
2.
Cube: 8 vertices
3.
Triangular Pyramid: 4 vertices
4.
Cylinder: 0 vertices
5.
Cone: 1 vertex
6.
Sphere: 0 vertices
7.
Triangular Prism: 6 vertices
Final Answer Boxed:
\[
\boxed{\text{Draw small circles at all vertices of each shape as described above.}}
\]
