Measuring an Angle
You can measure an angle between two straight lines drawn on the screen. To do this:
1 Display the [TOOL MENU: MEAS/DRAW] screen.
2 Tap [ANGLE].
3 Specify two arbitrary points (A and B in the figure) on
the screen so that the first line is drawn.
The two points you specify become the starting and end
points of a line.
4 Specify two arbitrary points (C and D in the figure) on
the screen so that the second line is drawn.
When the second line is drawn, the angle between two lines
is displayed.
In cases such as if the two lines are completely overlapped
or parallel, the angle cannot be measured and "NG" is
displayed.
To continue measurement, repeat steps 3 and 4.
5 To terminate measurement, tap [CLOSE] to redisplay the
[TOOL MENU: MEAS/DRAW] screen.
