Pythagorean Theorem Worksheet
Introduction
The Pythagorean Theorem is a fundamental principle in mathematics that relates the lengths of the sides of a right triangle. It states that in a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the lengths of the other two sides. This can be represented by the formula: a² + b² = c², where c is the length of the hypotenuse and a and b are the lengths of the other two sides.

a) 4 units
b) 6 units
c) 8 units

2. True or False: A right triangle can have side lengths of 6, 8, and 10.
3. True or False: The Pythagorean Theorem can be applied to any triangle, regardless of its angle measures.
Section 4: Problem Solving
1. A right triangle has one leg measuring 9 cm and the other leg measuring 12 cm. Calculate the length of the hypotenuse.
2. If you know the lengths of the two legs of a right triangle are x and y, express the length of the hypotenuse in terms of x and y.
3. A ladder leans against a wall, reaching a height of 15 feet. If the base of the ladder is 9 feet away from the wall, find the length of the ladder.
Section 5: Application
1. A triangular garden has sides measuring 7 meters, 24 meters, and 25 meters. Determine if it is a right triangle using the Pythagorean Theorem.
2. You want to build a rectangular patio that is 10 meters wide and 14 meters long. If you need to place a diagonal support beam, find the length of the beam using the Pythagorean Theorem.
