Question 8 from the Test

Geometry 10-1 Solid Geometry

Definitions Face: the flat side of a figure Edge: a straight line connecting sides Vertex: a corner where edges intersect

Basic Shapes Prism: polygon bases, parallelogram faces Cylinder: circle bases, curved face Pyramid: polygon base, triangle faces connected to a vertex Cone: circle base, curved side connected to a vertex

Bases The bases of a prism are the non-rectangle sides (if there are any). The base of a pyramid is the non-triangle side (if there are any).

The Name of the Game Prisms and pyramids are named according to the shape of the base.

Example Classify the solid shape. pentagonal pyramid vertices: A, B, C, D, E, F base: ABCDE edges:

Example Classify the solid shape. vertex: N cone edges: cones don’t have edges base: M M

Definition A net is a diagram of the surfaces of a three- dimensional figure that can be folded to form the three-dimensional figure. The net of a cube.

Definition A cross section is the intersection of a three- dimensional figure and a plane. This cross section is a pentagon

Examples Describe each cross-section:
