to draw a geometric figure around another figure so that the two are in contact but do not intersect
a hole (usually in wood) with the top part enlarged so that a screw or bolt will fit into it and lie below the surface
(1) A hole consisting of two depths so that the top of the head of an inserted bolt or screw will be flush with the outside surface. (2) A bit for enlarging the upper part of a hole.
the length of a straight line passing through the center of a circle and connecting two points on the circumference
A regular oval shape, traced by a point moving in a plane so that the sum of its distances from two other points is constant, or resulting when a cone is cut by an oblique plane which does not intersect the base.
A modeling process that creates a three-dimensional form by defining a closed two-dimensional shape and a length.
The numerical value of the ratio of the circumference of a circle to its diameter of approximately 3.14159.
a polyhedron with two congruent and parallel faces (the bases) and whose lateral faces are parallelograms
A type of 3D CAD modeling that represents the volume of an object, not just its lines and surfaces. This allows for analysis of the object's mass properties.
Cartesian Coordinate System
a coordinate system for which the coordinates of a point are its distances from a set perpendicular lines that intersect at the origin of the system
Software that allows you to create engineering, architectural, and scientific designs
Constant, non-numerical relationships between the parts of a geometric figure. Examples include parallelism, perpendicularity, and concentricity.
A number value, or algebraic equation that is used to control the size or location of a geometric figure.
