[Blindmath] the unit circle - SVGDraw01

[Richard Baldwin]

Hi David,

You can draw anything that can be drawn with lines, rectangles, circles,
ellipses, polylines, polygons, SVG paths, or text.

The only symbols that are available are the typical keyboard characters
treated as text. However, if you can construct your own square-root symbol
using three lines or preferably as a polyline, you can save it as an svg
file and import it later when you need it. After importing it, you can
scale and translate it to the size and location that it needs to be.

If you want an arrow head on the pointing line, you might also consider
creating it as a polyline, saving it as an svg file, and then importing,
rotating, scaling, and translating it later to the size and location that
it needs to be.
