## Installation See `installation.md`.

line = Line(dot_a.get_center(), dot_b.get_center(), color=YELLOW) ray = Line(dot_a.get_center(), RIGHT * 4, color=GREEN, stroke_width=6) segment = Line(dot_a.get_center(), dot_b.get_center(), color=PURPLE) &lt;code&gt;tools/geometry_utils

## Interactive Demo (in `interactive.ipynb`) Use widgets to plot points and toggle line/ray/segment. color=YELLOW) ray = Line(dot_a.get_center()
