LINR 3 | Lesson 4 | Supplement 1

Ideas about the triangle

Goal is to wake up your thinking about coordinate geometry, triangles, linear systems, linear inequalities.  Concepts could include the following:

  • coordinates of vertices
  • equations of lines of the sides
  • inequalities that define the triangle perimeter and shaded area inside
  • side lengths (using of vertices and pythagorean theorem to calculate)
  • type of triangle (right, scalene, isosceles, etc.)
