Classify 3-D Figures

Front

What is a prism?

Back

A prism is a 3-D figure with two parallel, congruent bases connected by rectangular faces.

Front

What is a pyramid?

Back

A pyramid is a 3-D figure with a polygonal base and triangular faces that meet at a single point called the apex.

Front

What is a cone?

Back

A cone is a 3-D figure with a circular base that tapers smoothly to a point called the apex.

Front

What is a cylinder?

Back

A cylinder is a 3-D figure with two parallel circular bases connected by a curved surface.

Front

What is a sphere?

Back

A sphere is a perfectly round 3-D figure where every point on the surface is equidistant from the center.

Front

How many faces does a prism have?

Back

A prism has at least 5 faces: 2 bases and at least 3 rectangular faces.

Front

How many faces does a pyramid have?

Back

A pyramid has at least 4 faces: 1 base and at least 3 triangular faces.

Front

How many edges does a cone have?

Back

A cone has 1 edge (the circular base) and 1 vertex (the apex).

Front

How many edges does a cylinder have?

Back

A cylinder has 2 edges (the circular bases) and no vertices.

Front

What is the difference between a prism and a pyramid?

Back

A prism has two parallel bases, while a pyramid has one base and triangular faces that converge at an apex.
