  1. Draw one triangle with an area of 12 square units. Try to draw a non-right triangle. (.ggb)
     
  2. Here are three copies of the same triangle. The triangle is rotated so that the side chosen as the base is at the bottom and is horizontal. Draw a height that corresponds to each base. (.ggb)
