On a coordinate grid, graph these points to create a triangle:

  1. What kind of triangle is it?

    Look at the angles of the triangle.

  2. Where could you add a fourth point so that when the points are connected you will make a rectangle?

    Plot point D onto the coordinate grid so that points , , , and form a rectangle.

  3. What point can you add to create a trapezoid?

    Answers will vary. Plot point to make a possible trapezoid.

  4. Translate the original triangle units to the left and units down. Label the coordinates of the vertices of the new triangle.

    Move points , , and units to the left and units down.
