Answers
centimeters Answer: 1/100th of a meter
millimeters Answer: 1/1000ths of a meter
meter Answer: basis for metric system; = to 100 cm,
1000mm, 10 dm, etc.
decimeter Answer: 1/10th of a meter
American Society of Mechanical Engineers Answer: ASME
dekameter Answer: 10 meters
kilometer Answer: 100 dekameters; 1000 meters

2:1 Answer: double size
drawn to scale Answer: drawing an object to a set proportion
metric system Answer: decimal system of wights and
measures based on the meter and the kilogram; SI
(international system) linear unit is millimeter
lettering Answer: single stroke gothic; TOM Q. VAXY is all the
letters that are as tall as they are wide; drawn w/HB
foreshortened Answer: surfaces do not give a clear or
accurate representation of the size or shape of the surface or
features and should not be dimensioned; lines and surfaces
that are inclined to the picture plane appear this way
bisecting Answer: dividing into two equal parts; drawn by
setting compass length greater than half of line's length and
striking arc w/center at each endpoint, then drawing a line
perpendicular to the original line through the point where the
arcs crossed
equilateral Answer: all side lengths are equal
concentric Answer: having a common center
180º Answer: number of degrees in a triangle
