如何计算Right Triangle

learn.whatIsHeading

A right triangle has one 90° angle. The Pythagorean theorem (a² + b² = c²) relates its three sides: legs a and b, and hypotenuse c (opposite the right angle). Right triangles are fundamental in trigonometry, construction, and navigation.

分步指南

1. 1Hypotenuse: c = √(a² + b²)
2. 2Leg: a = √(c² − b²)
3. 3Angles: angle A = arctan(a/b), angle B = arctan(b/a), sum of angles = 180°
4. 4Area = (1/2) × base × height = (1/2) × a × b
