§ IED VOCABULARY §
31
Acute Triangle : A triangle that contains only angles that are less than 90 degrees.
Angle : The amount of rotation needed to bring one line or plane into coincidence with another, generally measured in radians or degrees.
Area : The number of square units required to cover a surface.
Axis : An imaginary line through a body, about which it rotates. 2. An imaginary line about which a regular figure is symmetrically arranged. 3. A fixed reference line for the measurement of coordinates.
Center of Gravity : A 3D point where the total weight of the body may be considered to be concentrated.
Centroid : A 3D point defining the geometric center of a solid.
Circle : A round plane figure whose boundary consists of points equidistant from the center
Circumscribe : A triangle located round a polygon such as a circle. 2 To draw a figure around another, touching it at points but not cutting it.
Cylinder : A solid composed of two congruent circles in parallel planes, their interiors, and all the line segments parallel to the axis with endpoints on the two circles.
Density : The measure of mass density is a measure of mass per volume.
Diameter : A straight line passing from side to side through the center of a circle or sphere.
Ellipse : A shape generated by a point moving in a plane so that the sum of its distances from two other points (the foci) is constant and equal to the major axis
Fillet : A curve formed at the interior intersection between two or more surfaces.
Inscribe : To draw a figure within another so that their boundaries touch but do not intersect.
Mass : The amount of matter in an object or the quantity of the inertia of the object.
Meniscus : The curved upper surface of a liquid column that is concave when the containing walls are wetted by the liquid and convex when not.
Obtuse Triangle : A triangle with one angle that is greater than 90 degrees.
Parallelogram : A four-sided polygon with both pairs of opposite sides parallel.
Pi : The numerical value of the ratio of the circumference of a circle to its diameter of approximately 3.14159.
Polygon : Any plane figure bounded by straight lines.
Principal Axes : The lines of intersection created from three mutually perpendicular planes, with the three planes’ point of intersection at the centroid of the part.
Prism : A solid geometric figure whose two ends are similar, equal, and parallel rectilinear figures, and whose sides are parallelograms.
Quadrilateral : A four-sided polygon.
Radius : A straight line from the center to the circumference of a circle or sphere.
Rectangle : A parallelogram with 90 degree angles. A square is also a rectangle.
Regular Polygon : A polygon with equal angles and equal sides.
Right Triangle : A triangle that has a 90 degree angle.
Round : Two or more exterior surfaces rounded at their intersections.
Square : A regular polygon with four equal sides and four 90 degree angles.
Surface Area : The squared dimensions of the exterior surface
Tangent : A straight or curved line that intersects a circle or arc at one point only.
Title Block : A table located in the bottom right-hand corner of an engineering drawing that identifies, in an organized way, all of the necessary information that is not given on the drawing itself. Also referred to as a title strip.
Triangle : A polygon with three sides.
Vertex : Each angular point of a polygon, polyhedron, or other figure.
Volume : The amount of three-dimensional space occupied by an object or enclosed within a container.
Quadrilateral : A four-sided polygon.
