Experimenting with the Editor’s Buffer Capabilities

____ 31. Stop editing without saving edits. Then start editing the feature class with the single triangle again. This time select the Buffer command on the Editor drop-down menu. When asked for a distance, use 100 meters. Note the figure that is created, particularly its rounded corners. Every point on the line of the new polygon is 100 meters from the original triangle, measured along a line perpendicular to a side of the original triangle, or is on a circle with radius 100 meters with its center at a corner of the triangle. In the table, clear selections. Now use Buffer on the original triangle again (you have to select it), specifying a distance of −100 meters. Observe. Stop editing without saving edits.
