Squaring off a line or polygon
Square and Finish is a way of completing a polygon or closed line. It finishes a polygon or line by adding two new segments at 90degree angles. Square and Finish saves you time and ensures precision when creating squarecornered buildings.
Two other ways of creating square corners are to use either the Right Angle construction method, which creates each segment at a 90degree angle to the previous segment, or the Rectangle tool, which makes rectangular features.
Steps:

These steps can be used to create vertices in either lines or polygons:
To create a vertex in a line
Click a line feature template in the Create Features window and click the Line tool .
To create a vertex in a polygon
Click a polygon feature template in the Create Features window and click the Polygon tool .
 Click the Straight Segment construction method on the Editor toolbar.
 Digitize at least two segments.

Rightclick anywhere on the map and click Square and Finish.
The angles from the first vertex and the last vertex are squared. A new vertex is added, and the polygon or polyline is finished where the resulting segments intersect.
