kFixing a Measurement of a Figure
By “fixing a measurement” we mean that a constraint is placed on the figure. For example, if we fix (constrain) a point to a circle and move the circle, the point will also move.
The following example shows how to fix the size of an angle of a triangle.
u To fix the measure of an angle of a triangle
(1)Draw the triangle.
(2)Select side AB and then select side BC.
(3)Input 90 into the measurement box, and then select the check box to the right of it.
• This fixes the measure of angle B at 90 degrees.
A highlighted check box indicates the measurement is fixed (constrained).
