**Pythagorean Theorem**

a^{2} + b^{2} = c^{2}

*Note: Problems 2.1–2.3 refer to right triangle XYZ in the diagram below.*

**2.1** Identify the hypotenuse of the triangle and justify your answer. Then, classify the remaining sides of the triangle.

The hypotenuse of a right triangle is its longest side, and it is always located opposite the right angle. A small square drawn at a vertex of a figure indicates a right angle, so in this diagram, is a right angle. Therefore, the side opposite angle *Y* is the hypotenuse: . Note that is visibly longer than either of the ...
