Vocabulary

Three-Dimensional Figures - can be defined as a solid figures or objects or shapes that have three dimensions – length, width, and height.

Two-Dimensional Figures - are plane figures that have length and width but no depth.

Cone - a 3-D figure with one circular base connected by a curved side to a single vertex. 

Prism - a 3-Dimensional figure with at least two parallel, congruent faces that are polygons.

Pyramid - 3-Dimensional figure with one face that is a polygon, and the other faces are triangles.

Face - a flat surface.

Edge - where two planes intersect in a line.

Vertex - where 3 or more planes intersect at a point.

Concepts

Identify 3-dimensional figures/nets of 3D figures, based on their properties.

Rules

1. Determine the number of faces, vertices and edges for each figure.
2. Identify the correct net for the given information.

Example

Select the correct net for the shape that has:
5 faces, 5 vertices, and 8 edges

Solution

The shape folds so that the sides come together to form an edge and the vertices all come together to form the solid.
