Using the Measurement Box
u To unlock all objects on the screen
Perform the following operation:
K(Option) – 4:Clr Constraint.
This unlocks all locked settings.
Note
The above operation unlocks both measurements you locked manually, as well as objects
that are locked automatically whenever they are drawn. For example, the above operation
unlocks all of the following lock conditions.
• The lock that is applied when you draw a rectangle that keeps its opposing sides equal
(opposing side congruence lock)
• The lock that is applied when you draw an isosceles triangle (ABC) that keeps side AB and
side BC equal (side AB and side BC congruence lock)
• The lock that is applied when you draw an infi nite line that keeps the line passing through
two points (point A and point B) (infi nite line and point A, B incidence lock)
• The relationship between the line segment and perpendicular bisector that is formed when
you select a line segment and perform the following operation:
4(Construct) – 1:Perp
Bisector
• The (locked) similarities of objects when you select the objects and perform the following
operation:
5(Transform) – 5:Dilation
Pasting Measurements into a Screen Image
You can use the procedures in this section to paste object measurements into the image on
the screen. The measurements change dynamically as you manipulate the object.
The following types of measurements can be pasted into a screen image: coordinates,
distance/length, slope, equation, vector components, radius, circumference, perimeter, area,
angle, supplementary angle.
u To paste a measurement into a screen image
Example: To paste an internal angle measurement into a screen image
1. Draw a triangle and select two of its sides.
2. Press
J to display the measurement box.
