CONE

Three dimensional figure with a single base tapering to an apex. The base can be any simple closed curve. Often the word cone refers to a right circular cone.

BOX

Formally, a polyhedron for which all faces are rectangles.

TRIANGLE

A polygon with three sides.

SEMI-CIRCLE

Half a circle. That is a 180 degrees arc.

RIGHT PYRAMID

A pyramid that has an open aligned directly above the center of the base.

RIGHT TRIANGLE A triangle which has a right 90

degrees interior angle.

HEXAGON

A polygon with six sides.

DODECAGON

A polygon with 12 sides.

DISC

Union of a circle and it’s interior

ANGLE

2 rays sharing a common endpoint. Angles are typically measured in degree or radians.

CIRCULAR CONE

A cone which has a circle as it’s base.

RHOMBUS

A parallelogram with four congruent sides.

PERPENDICULAR

At a 90 degree angle.

QUADRANT

The four sections into which the x-y plan is divided by the x and y axis.

REGULAR PYRAM

ID

A pyramid with a base that is a regular polygon. The apex is not necessarily directly above the center of the base.

RIGHT ANGLE

A 90 degree angle.

POLYGON

A closed plane figure for which all sides are line segments.

DECAGON
