Student Outcomes

  • Students show the area formula for a triangular region by decomposing a triangle into right triangles.  For a given triangle, the height of the triangle is the length of the altitude.  The length of the base is either called the length base or, more commonly, the base.
  • Students understand that the height of the triangle is the perpendicular segment from a vertex of a triangle to the line containing the opposite side.  The opposite side is called the base.  Students understand that any side of a triangle can be considered a base and that the choice of base determines the height.
