With GeometrySketch (subject to a fee after a one-month trial period), you can easily and intuitively create geometric drawings using a protractor, compass, and ruler. Shape tools also allow you to quickly create lines, rectangles, and polygons. Resulting documents can be printed, exported, saved, or pasted into another program via the clipboard. Worksheets, pages from textbooks or workbooks can be inserted and edited as images or PDF files directly, by drag and drop or via the clipboard. Coordinate systems can be generated and changed using a variety of setting options.
