In the Classroom

Pre-Experience (Things to Look Out For):

  • What is a right triangle? What do we call the diagonal side? How about the two other sides?

  • What is the Pythagorean Theorem?

  • What is its purpose?

  • Can you envision reorganizing it in any way to use it slightly differently?

Post-Experience (Things to Think About):

  • What are the common combinations of numbers you might see in a question about the Pythagorean theorem?

  • Why do you think the Pythagorean Theorem always holds? Can you show why it is true?

  • What are some real-world situations in which solving for the length of a right triangle’s leg is useful?
