EGT 120 EXAM 2 QUESTIONS WITH CORRECT ANSWERS LATEST UPDATE 2025/2026
The basic geometric elements and forms used in engineering design - Answers Engineering
geometry
object relates to the positions of its component geometric elements in space - Answers shape
description
based on the primitive forms, points, lines, and planes which are combined to create more
complex forms. - Answers shape description
developed through orthographic, pictorial or other projection techniques - Answers shape
description
In order to locate points lines planes or other geometric forms their positions must first be
referenced to some known position called - Answers reference point
commonly used in mathematics and graphics, locates the positions of geometric forms in 2d
and 3d space - Answers Cartesian coordinate system
this is assigned the coordinate values of 0,0 - Answers origin
used to determine the positive direction of the axes - Answers right hand rule
used to locate points in any plane - Answers polar coordinates
involve one angles and two distances - Answers cylindrical coordinates
are always referenced to a previously defined location and are sometimes referred to as delta
coordinates - Answers relative coordinates
delta coordinates - Answers changed coordinates
CAD systems normally use two types of coordinate systems - Answers world and local systems
stationary or reference system where the geometry is defined or stored. also use a set of three
numbers (x,y,z) - Answers world coordinate
a moving system that can be positioned anywhere in 3d space by the user to assist in the
construction of geometry - Answers local coordinate
theoretical location that has neither width height nor depth - Answers point
a point - Answers node
is a straight infinite line that extends into infinity from a specified point - Answers ray
exists when a straight line is in contact with a curve at a single point - Answers tangent
