An equilateral triangle is a triangle with all three sides equal and all three angles equal to 60°. Plug a and c into the equation, squaring both … - equal sides. The area of a triangle is half of the product of the length of the base and the height. Our calculator will solve geometrical problems in a few seconds. Questionnaire. Then click Calculate. - height = bisector = median. Examples of calculating isosceles triangles: angle α and base c; base c and arm a; height and arm a 6. To recall, an equilateral triangle is a triangle in which all the sides are equal and the measure of all the internal angles is 60°. Solution: Given that, the side length “a” is 4 cm. So all you need to do is calculate that middle line. Calculate the height of a triangle whose area is 25 cm² and the given length of its base is 10 cm. Another way to calculate the exterior angle of a triangle is to subtract the angle of the vertex of interest from 180°.
