*Note: Drawing to Scale

With the help of constraints, drawing figures to scale happens automatically. If line AB is constrained to a distance of 4 and line CD to a distance of 8, CD will **automatically** be twice as long as AB.

The same is true of angles. If you want a triangle with angles 30°, 60° and 90° simply constrain two of them (the software will figure out the third).

Of course you may want to purposefully draw a figure that is **not** to scale. This is where the annotations come in. Using annotations instead of constraint you can set a distance or angle to be anything you want!
