Learning Targets and Learning Criteria 

Students are successful when they can…
 demonstrate the relationship of the three side lengths of any right angle by the use of visual models.
 apply algebraic reasoning to relate the visual model to Pythagorean Theorem.
 determine if a given triangle is a right triangle using Pythagorean Theorem.
 explain a proof of the converse of the Pythagorean Theorem.
 apply the Pythagorean Theorem to find an unknown side length of a right triangle.
 identify the hypotenuse as the side opposite the right angle in a triangle.
 draw a diagram and use the Pythagorean Theorem to solve realworld problems involving right triangles, including threedimensional figures.
 connect any two points on a coordinate grid to a third point so that the three points form a right triangle.
 apply the Pythagorean Theorem with the characteristics of a right triangle to find the distance between the original two points.
