الأسئلة الشائعة — Right Triangle Calculator
How do I solve a right triangle?
A right triangle has one 90° angle (C), two acute angles (A and B where A+B=90°), and three sides: a (opposite A), b (opposite B), and c (hypotenuse, the longest side). Given any 2 known values, all others can be found using: the Pythagorean theorem (a²+b²=c²), sine (sin A = a/c), cosine (cos A = b/c), and tangent (tan A = a/b).
What are the standard right triangle ratios?
Common right triangle ratios: 3-4-5 (angles ≈ 36.87°, 53.13°), 5-12-13, 8-15-17. Special triangles: 45-45-90 (sides ratio 1:1:√2) and 30-60-90 (sides ratio 1:√3:2). These ratios allow exact computation without a calculator.
How is area calculated for a right triangle?
Area = (1/2) × base × height = (1/2) × a × b, where a and b are the two legs (not the hypotenuse). For a right triangle with legs 3 and 4, area = (1/2)(3)(4) = 6 square units.
