Area of a Right Triangle Calculator
Calculate the area of a right triangle using different combinations of sides and angles.
Right Triangle Area Formulas
Base and Height
A = ½ × b × h
where b is the base and h is the heightTwo Sides
A = ½ × a × b
where a and b are the two sidesSide and Angle
A = ½ × a² × tan(θ)
where a is the side and θ is the angleHypotenuse and Angle
A = ½ × c² × sin(θ) × cos(θ)
where c is the hypotenuse and θ is the angle
Note: A right triangle has one 90° angle, and the area can be calculated using any of these methods depending on the known values.
