What is the Pythagorean Theorem?

Back

The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b). Formula: a² + b² = c².

What is the length of the hypotenuse in a right triangle with legs of length 3 and 4?

Back

The length of the hypotenuse is 5, calculated using the formula: c = √(3² + 4²) = √(9 + 16) = √25 = 5.

What is the relationship between the angles in a right triangle?

Back

In a right triangle, one angle is 90 degrees, and the other two angles are acute, meaning they are less than 90 degrees.

If one leg of a right triangle is 6 and the hypotenuse is 10, what is the length of the other leg?

Back

The length of the other leg is 8, calculated using the formula: b = √(c² - a²) = √(10² - 6²) = √(100 - 36) = √64 = 8.

What is the distance formula in a coordinate plane?

Back

The distance formula is used to find the distance between two points (x₁, y₁) and (x₂, y₂): d = √((x₂ - x₁)² + (y₂ - y₁)²).
