HOW TO USE THE SCALE ON THE DRAWING. ANGLE TRIANGLES
Scale is the relationship between an object and the real object drawn. It is used as scale, usually a fractional number whose numerator is unity, for example, 1 / 50, in this example the real object is 50 times larger than the object drawn. Sunday, May 24, 2009

The instrument used to measure the scale in the drawing is called scaler and can find various scales ranging has allowed us to draw different objects in different sizes, but accurate measurements.
Each basic scale has variations that are generated by adding or removing a zero to the basic scale derecah, eg
base scale: 1 / 100
variations: 1 / 1 - 1 / 10 - 1 / 1000 - 1 / 10000 scale
base: 1 / 50
variations: 1 / 5 - 1 / 500 - 1 / 5000 - 1 / 50000 scale
base: 1 / 75
variations: 1/7.5 - 1 / 750 - 1 / 7500 - 1 / 75000 scale
base: 1 / 125
variations: 1/12.5 - 1 / 1250 - 1 / 12500
base scale: 1 / 20
variations: 1 / 2 to 1 / 200 - 1 / 2000 - 1 / 20000 scale
base: 1 / 25
variations: 1/2.5 - 1 / 250 to 1 / 2500 - 1 / 25000
There are other scales that are not as commercial how are you which are generally used in surveying
How we use the scale to draw?
1 -. When we are given a drawing exercise, we identify the scale at which we are asking that we draw, then we must locate the scaler Jan scale of measurement that can be used.
2 -. We must remember that everything is drawn concerning the exercise that being conducted must be drawn on the scale that we indicated (line, circle radii, diameters, quadrilaterals, distances, coordinates of points, etc).
3 -. The only element that does not support drawing scale and always measured the same way, regardless of the scale on which are the angles work. These will be measured co simpre a carrier and with the same grading system.
4 -. in the case of the exercise indicates a fucking coordinate (X, Y), this should be measured on the same scale that are working the exercise.
