Area of a triangle calculator

The area of a triangle calculator will help you calculate the surface of a triangle using the base and height, three sides, two sides and an angle or two angles and a side.

How do you calculate the area with the base and height?

To calculate the area of a triangle with the base and height, you can multiply 0.5 by the base and then multiply that by the height.

Area = ½ × base × height

How do you calculate the area with two sides and an angle?

To calculate the area of a triangle with two sides and an angle, you can multiply 0.5 by side 1, multiply by side 2 and then multiply by the sin of the angle.

Area = ½ × side 1 × side 2 × sin(angle)

How do you calculate the area with three sides?

Area = ½ × √((side 1 + side 2 + side 3) × (-side 1 + side 2 + side 3) × (side 1 - side 2 + side 3) × (side 1 + side 2 - side 3))

How do you calculate the area with two angles and a side?

Area = side² × sin(angle 1) × sin(angle 2) / (2 × sin(angle 1 + angle 2))
