Note
A value that shows the area of an object whose lines intersect is indicated by double asterisks
(``) to the left of the value. This indicates that the value may not indicate the correct area.
k Specifying a Measurement of an Object
In the following examples, we specify the angle of a triangle and the length of one side of a
triangle.
u To specify the angle of a triangle
1. Draw a triangle.
2. Select side AC and then select side BC.
3. Press J to display the measurement box.
• This displays the size of ∠ACB (in degrees) in the
measurement box.
4. Input the value you want to specify for ∠ACB (in degrees) into the measurement box and
then press w.
• In this example we input 90, which makes ∠ACB 90 degrees.
