1. Page 134 First, some definitions.
Right Triangle: a triangle with a right angle (90 degrees) as the largest angle. The right angle is often marked with a square.
Hypotenuse: The longest side of a right triangle – the side across from the right angle.
Legs: The two shorter sides of a right triangle that form the right angle.

2. The leg across from ∠A is labeled with a small a.
The leg across from ∠B is labeled with a small b.
The hypotenuse is labeled with a small c.

3. About 550 BC, Pythagoras, a Greek philosopher, mathematician, and astronomer, figured out that the lengths of the sides of a right triangle are connected by a formula. The Pythagorean Theorem is named after him.

Sides of 4 and 11. The third side is a leg. This means the hypotenuse is 11.
Sides of 4 and 11. The third side is the hypotenuse.
