Pythagorean Theorem
Learning Objective
I can use the Pythagorean Theorem to find the missing side length of a right triangle.
Key Concepts
The Pythagorean Theorem applies to right triangles, which contain one angle that measures 90 degrees.
The longest side of a right triangle is called the hypotenuse, and it is always opposite the right angle.
The Pythagorean Theorem states that a² + b² = c², where c represents the length of the hypotenuse, and a and b represent the lengths of the triangle's other two sides.
