I can use visual models to demonstrate the relationship of the three side lengths of any right triangle.
I can use algebraic reasoning to relate the visual model to the Pythagorean Theorem.
I can use the Pythagorean Theorem to determine if a given triangle is a right triangle.
I can apply the Pythagorean Theorem to find an unknown side length of a right triangle.
I can use the Pythagorean Theorem to solve real-world problems.
I can use the Pythagorean Theorem within a 3-D figure.
I can connect any two points on a coordinate grid to a third point so that the three points form a right triangle.
I can use a right triangle and the Pythagorean Theorem to find the distance between two points.
