Pythagorean Theorem Finding Hypotenuse

Discovering the Pythagorean Theorem

Exploring the relationship between the sides of a right triangle and the theorem's applications in geometry and real-world scenarios.

Pythagorean Theorem:

• Discovering the Pythagorean Theorem: a fundamental concept in geometry
• Formula: a² + b² = c²
• Key terms: hypotenuse, legs
• Deprecated: a² - b² = c²

Multiple Choice

What is the formula for the Pythagorean Theorem?

• a² + b² = c²

• a² - b² = c²

• a² + b² + c² = 0

• a² - b² + c² = 0

Pythagorean Theorem:

a² + b² = c² is the formula for the Pythagorean Theorem. It is used to find the length of the hypotenuse in a right triangle. The theorem is named after the Greek mathematician Pythagoras. It is one of the most famous and widely used theorems in mathematics. Remember, the sum of the squares of the two legs is equal to the square of the hypotenuse!

Applying the Pythagorean Theorem

• Step 1: Identify the two legs of the right triangle.
• Step 2: Square the length of each leg.
• Step 3: Add the squared values of the legs.
• Step 4: Take the square root of the sum to find the length of the hypotenuse.

Multiple Choice

What is the purpose of Step 4 in discovering the Pythagorean Theorem?

• To identify the two legs of the right triangle

• To square the length of each leg

• To add the squared values of the legs

• To find the length of the hypotenuse

Pythagorean Theorem:

Step 4: To find the length of the hypotenuse. The hypotenuse is the longest side of a right triangle and can be calculated by adding the squared values of the two legs and then taking the square root of the sum. This theorem is named after the Greek mathematician Pythagoras.
