Our Right Triangle Calculator makes it simple to solve for unknown properties. Just enter the lengths of the two legs (sides 'a' and 'b'), and instantly get the hypotenuse, acute angles, area, and perimeter. Ideal for geometry, construction, and trigonometry tasks.
Formula:
Given legs 'a' and 'b':
- Hypotenuse (c):
c = √(a2 + b2)(Pythagorean Theorem) - Area:
Area = (1/2) × a × b - Perimeter:
Perimeter = a + b + c - Angle A (opposite side a):
A = arctan(a / b) - Angle B (opposite side b):
B = arctan(b / a)orB = 90° - A
Where 'a' and 'b' are the lengths of the two legs, 'c' is the hypotenuse, and 'A' and 'B' are the acute angles.
