What is Angle
300
A 3D point where the total weight of the body may be considered to be concentrated.
What is Center of Gravity
400

What is Axis
400
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
What is Ellipse
400
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.
What is Title Block
400
A triangle that contains only angles that are less than 90 degrees.
What is Acute Triangle
400
1. 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.
What is Circumscribe
500
The lines of intersection created from three mutually perpendicular planes, with the three planes’ point of intersection at the centroid of the part.
What is Principal Axes
500

What is Fillet
500
Each angular point of a polygon, polyhedron, or other figure.
What is Vertex
500
The curved upper surface of a liquid column that is concave when the containing walls are wetted by the liquid and convex when not.
