Prepare a Presentation

  • Select one of your conclusions about what happens to the area of a triangle when you change one or more variables.
  • Be prepared to demonstrate your conclusion using the Triangle interactive, and to support your thinking mathematically.

Challenge Problem

Suppose the base of a triangle lies on one of two parallel lines, and the vertex opposite the base lies on the other parallel line.

  • If you slide the vertex along the line, what do you think will happen to the area of the triangle? Use the Triangle interactive to test your prediction.
  • Explain your results.
