Further Guidance
Since there are so many possibilities to test, it is useful to start by considering the shapes that can be generated just from one triangle. For example:
a. Test what happens when the half-square is reflected across each side. For each result (original plus image), draw a diagram and describe the shape that you get.
If you know a name for the result, state it.
b. The point in the middle of each side is called its middle point, or midpoint for short. Try rotating the half-square 180° about the midpoint of each side to make a
new shape. For each result, draw a diagram. If you know its name, write it near your new shape.
c. Repeat parts (a) and (b) with each of the other triangles offered by the Shape Factory.
