Understanding the Pythagorean Theorem
What Is the Pythagorean Theorem?
The Pythagorean theorem is a fundamental principle in geometry that relates the lengths of the sides of a right triangle. It states that:
- a² + b² = c²
Here, a and b are the lengths of the legs (the two sides forming the right angle), and c is the length of the hypotenuse (the side opposite the right angle).
Importance of the Pythagorean Theorem
The theorem is crucial because:
- It helps in calculating the length of an unknown side in right triangles.
- It is widely used in fields such as engineering, architecture, navigation, and computer graphics.
- It provides a foundation for understanding distance calculations in coordinate geometry.

Sample Pythagorean Theorem Worksheet with Answers PDF Content
Sample Problems Included
Below are examples of problems typically found in a worksheet with answers:
1. Find the hypotenuse of a right triangle with legs of 3 cm and 4 cm.
2. A ladder is 13 meters long, and it leans against a wall, forming a right triangle. If the base is 5 meters from the wall, find the height the ladder reaches on the wall.
3. The coordinates of two points are A(2, 3) and B(5, 7). Find the distance between them using the Pythagorean theorem.
4. A right triangle has one leg measuring 6 inches and the hypotenuse measuring 10 inches. Find the length of the other leg.
5. Word problem: A rectangular garden is 8 meters long and 6 meters wide. What is the length of the diagonal across the garden?
Sample Answers
- Problem 1: Hypotenuse = √(3² + 4²) = √(9 + 16) = √25 = 5 cm.
- Problem 2: Height = √(13² - 5²) = √(169 - 25) = √144 = 12 meters.
- Problem 3: Distance = √((5 - 2)² + (7 - 3)²) = √(3² + 4²) = √(9 + 16) = √25 = 5 units.
- Problem 4: Other leg = √(10² - 6²) = √(100 - 36) = √64 = 8 inches.
- Problem 5: Diagonal = √(8² + 6²) = √(64 + 36) = √100 = 10 meters.
