Kuinka laskea Right Triangle
Mikä on Right Triangle?
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.
Vaiheittainen opas
- 1Hypotenuse: c = √(a² + b²)
- 2Leg: a = √(c² − b²)
- 3Angles: angle A = arctan(a/b), angle B = arctan(b/a), sum of angles = 180°
- 4Area = (1/2) × base × height = (1/2) × a × b
