Frequently Asked Questions
What is the Pythagorean Theorem?
In a right-angled triangle, the square of the hypotenuse is equal to the sum of the squares of the other two sides: a² + b² = c².
How are the acute angles calculated?
Angles are computed using inverse trigonometric functions: angle α = arctan(a / b) in degrees.
