It is also called ‘Right Hypotenuse Theorem’. This theorem implies right angled triangles. In every triangle, longer side is opposite the larger angleĪnd smaller side opposite to the smaller angle. Triangles, the base should be extended in order to draw altitude.Īltitude is also called as height of the triangle.īh. In some cases like in the case of an Obtuse angled Triangle bisect the angle and the base too.įor a right angled triangle with right angle any side on theīase, altitude is measured as the length of the perpendicular. The altitude of an equilateral triangle and an isosceles The sum of all the 3 angles of a triangle => A + B + C = 180Īn altitude of a triangle is the line joining the base One of theĪngles = 90 degrees and the longest side is called ‘hypotenuse’ opposite to the right angle. If a triangle has one right angle, then it is said to be a Right Angled Triangle.
