The second example shows how to view the measurements of a line segment.
u To display the area of a triangular area
You can use the measurement box to display the area of a triangle formed by any three points you select on the display.
Example: To use the parallelogram ABCD, in which sides AD and BC are parallel, to determine the areas of the triangles formed by side AD and point B, and side AD and point C
(1)Draw the parallelogram.
• If you need to, select [Edit] and then [Clear All] before beginning this example.
