Critique

Review your work from the Self Check and think about these questions.

  • What is the minimum number of vertices your figure or design needs to have one vertex in each quadrant?
  • What do you know about numbers that have equal absolute values?
  • How do you know your figure or design meets all of the criteria?
  • Does your explanation show how your figure or design meets each of the criteria?
  • Is your work neat and labeled clearly?
  • Can you make a different figure or design that meets the same criteria?

Revise Your Work

Work with your partner to revise your work based on the feedback that both of you got on this problem.

  1. Create a figure or design on the coordinate plane that satisfies the criteria below.
    • At least one vertex has coordinates that include a number and its opposite.
    • At least one vertex has coordinates that are both nonintegers.
    • At least one vertex is in each quadrant.
    • At least two vertices have x-coordinates that have equal absolute values.
    • At least two vertices have y-coordinates that have equal absolute values.
  2. Label each vertex with its ordered pair, and explain how your figure or design meets the criteria.

Use the Coordinate Plane Plotter interactive if you find it to be helpful.
