Components
Each of the renderable components has its own file in the ruby/render/assignment directory.
Equilateral Triangle
The triangle should be equilateral, with the origin at the center of mass.
The height is side_length * sqrt(3)/2
The center of mass is one third from the bottom.
Rectangle
Ellipse
Note: to produce the reference images I used

Bézier Curve
Point2
To support Bézier curves you will want to implement Point in point2.rb. You may wish to use Ruby's convenient Struct construct.
You should be able to construct a Point2 with an x and a y and be able to access those values.
