Question

3d figures practice assignment

a is a three-dimensional figure whose surfaces are polygons.

each polygon is a of the polyhedron.

an is a segment that is formed by the intersection of two faces.

a is a point where three or more edges intersect.

there are two types of faces: faces and

the side view or the faces that touch the base.

the 2 polygons that are congruent and parallel.

Explanation:

🆕 New Concept Discovered: Anatomy of Three-Dimensional Polyhedra
Identifying the parts and terminology of 3D solid shapes.

Step 1: Define a 3D figure with flat polygonal surfaces

A three-dimensional solid whose flat surfaces are all polygons is called a polyhedron.

• Sentence: "A polyhedron is a three-dimensional figure whose surfaces are polygons."

Step 2: Identify the flat surfaces of a polyhedron

Each individual flat polygonal surface that makes up the boundary of a polyhedron is called a face.

• Sentence: "Each polygon is a face of the polyhedron."

Step 3: Identify the line segments where surfaces meet

The line segment where two flat faces intersect is called an edge.

• Sentence: "An edge is a segment that is formed by the intersection of two faces."

Step 4: Identify the corner points

A corner point where three or more edges meet is called a vertex.

• Sentence: "A vertex is a point where three or more edges intersect."

Step 5: Classify the two main types of faces

In three-dimensional prisms and pyramids, we distinguish between two types of faces: base faces and lateral faces.

• Sentence: "There are two types of faces: base faces and lateral faces."

Step 6: Define lateral faces

The faces on the sides of a 3D figure that connect the bases are called lateral faces. They represent the side views.

• Sentence: "Lateral faces are the side view or the faces that touch the base."

Step 7: Define base faces

The two identical, parallel polygons at the top and bottom of a prism that define its shape are called bases.

• Sentence: "Bases are the 2 polygons that are congruent and parallel."

Answer:

Here are the correct terms to fill in each blank from top to bottom:

1. polyhedron
2. face
3. edge
4. vertex
5. base (first box) and lateral (second box)
6. Lateral faces
7. Bases
