ALGEBRA - LESSON 45

What are three-dimensional figures sometimes called

• Plane Figures

• Space Figures

• Solid Figures

• Depth Figures

Describe what the face, edge, and vertex of a geometric solid is:

What does it mean by closed figure? (go back and read it again if you do not understand)

How many faces does a triangular prism have (that is the right-side "pie" shaped geometric solid in the "prism" section of the table)

for example, a 2D shape like a square has one face (which is the square shape), a cube is made of 6 squares or 6 faces (top, bottom, back side, front side, left side, and right side).

How many vertices does a pyramid have?

vertices are the points, apex, or corners of the solid.

Which shape has an "apex"?

How many edges does a hexagonal prism have?

remember: edges are the lines that make up the solid.
