altitude
The perpendicular distance from the base of a geometric figure to the opposite vertex.
base
The number being put to a power: 8^3=8x8x8, 8 is the base.
circumference
The distance around a circle: equal to pi times diameter.
cone
A solid figure with a circular base and one vertex.
cylinder
A solid figure with two parallel, congruent circular bases connected by a curved surface.
edge
The line segment along which two faces of a 3D shape intersect.
face
A flat surface of a 3D shape.
lateral area
The area of the lateral surface of a solid.
net
A connected arrangement of polygons in a plane that can be folded up to form a polyhedron.
pi
The ratio of the circumference of a circle to the length of its diameter: pi is about 3.14.
prism
A 3D shape whose two bases are congruent, parallel polygons in parallel planes and whose lateral faces are parallelograms.
pyramid
A polyhedron with one base that is a polygon and with lateral faces that are triangles which share a common vertex.
slant height
The length of a lateral edge of a conic solid.
solid figure
A three-dimensional shape.
sphere
A solid figure with all points the same distance from the center.
surface area
The sum of the areas of all the faces, or surfaces, of a solid figure.
vertex
The point where two sides meet.
volume
The number of cubic units needed to occupy a given space.
