Let abc be the lengths of the sides of a triangle. Depending on the length of the sides and the internal angles the area of a triangle varies from one triangle to another. Enter the length of the base and the adjacent angles 1 and 2 then click the Calculate button.
The unit of area is measured in square units for example m 2 cm 2 in 2 etc. The height of a right angled triangle can be calculated by using Pythagorus theorems that states. Calculate triangle from base and angle.
The side opposite the right angle is called the hypotenuse. A right-angled triangle is a triangle in which one angle is a right angle that is a 90-degree angle. A method for calculating the area of a triangle when you know the lengths of all three sides.
The point D lies on the side AC so that BC BD and DC 2. In triangle ABC all three side lengths are integers and angle A 60 degrees. Therefore the height of the triangle will be the length of the perpendicular side.
