square = Line[{{0, 0}, {1, 0}, {1, 1}, {0, 1}, {0, 0}}];
triangle = Line[{{1, 0}, {3, 0}, {2, 1}, {1, 0}}];

If you want solid squares and rectangles...
Show[Graphics[
{MediumBlue, Polygon @@ square,
VenetianRed, Polygon @@ triangle}],
AspectRatio -> Automatic,
Background -> Linen];
If you want the sides to be arrows...
Needs["Graphics`Arrow`"]
squaresides = Partition[#, 2, 1] & @@ square
{{{0, 0}, {1, 0}}, {{1, 0}, {1, 1}}, {{1, 1}, {0, 1}}, {{0, 1}, {0, 0}}}
trianglesides = Partition[#, 2, 1] & @@ triangle
{{{1, 0}, {3, 0}}, {{3, 0}, {2, 1}}, {{2, 1}, {1, 0}}}
Show[Graphics[

VenetianRed, Arrow @@ # & /@ trianglesides}],
AspectRatio -> Automatic,

The DrawGraphics package at my web site has Arrow routines for placing the
arrowheads anywhere along the side. If you are working with graphs or using
Combinatorica you may wish to use the CombinatoricaPlots package also at my
web site. It gives complete control of styles and labeling of edges and
vertices.
