Solve Right Triangles for a Side

The longest side of a right triangle is called the...

• leg A

• leg B

• hypotenuse

• right angle

The longest side of a right triangle is DIRECTLY ACROSS from the...

• right angle.

• acute angle.

• obtuse angle.

The Pythagorean theorem states that:

• The two smaller sides of a right triangle sum to equal the longest side.

• The squares of the two smaller sides of a right triangle sum to equal the square of the longest side.

What is the final step in solving this work for c?
a² + b² = c²
3² + 4² = c²
9 + 16 = c²
25 = c²

• Divide both sides by 2

• Take the square root of both sides
