How do you construct a 30 degree angle without the use of a protactor?
Use a ruler to make a right angle triangle of dimension 3,4,5 the angle adjacent to the side of 4 units length is 30 degrees.
What the area of a right angle triangle having a base dimension of 3 feet and height of 4 feet?
It is: 0.5*3*4 = 6 square feet

Has length no dimension no thickness?
Length IS a dimension (in space). It has no thickness.
What is a dimension line?
Lines that define the parameters of a dimension.Dimension lines are thin lines terminating in arrowheads. Place dimension lines no closer than 3/8" from the object outline. Parallel dimension lines should be a minimum of 1/4" apart. You may place parallel dimension lines more than 1/4" apart so long as the spacing between dimension lines is uniform throughout the drawing. Dimension lines are generally broken in the center of the line to provide a space for the dimension figure. Dimension figures for parallel dimension lines are staggered. In some structural or architectural drawings, you may find dimension figures placed above the dimension line.
