topSide :: Num r => Rectangle p r -> LineSegment 2 p r

leftSide :: Num r => Rectangle p r -> LineSegment 2 p r

bottomSide :: Num r => Rectangle p r -> LineSegment 2 p r

Oriented from *left to right*

rightSide :: Num r => Rectangle p r -> LineSegment 2 p r

The right side, oriented from *bottom* to top

sides :: Num r => Rectangle p r -> (LineSegment 2 p r, LineSegment 2 p r, LineSegment 2 p r, LineSegment 2 p r)

The sides of the rectangle, in order (Top, Right, Bottom, Left). The sides themselves are also oriented in clockwise order. If, you want them in the same order as the functions topSide, bottomSide, leftSide, and rightSide, use sides' instead.

sides' :: Num r => Rectangle p r -> (LineSegment 2 p r, LineSegment 2 p r, LineSegment 2 p r, LineSegment 2 p r)

The sides of the rectangle. The order of the segments is (Top, Right, Bottom, Left). Note that the segments themselves, are oriented as described by the functions topSide, bottomSide, leftSide, rightSide (basically: from left to right, and from bottom to top). If you want the segments oriented along the boundary of the rectangle, use the sides function instead.
