![]() The sum of all the sides is the perimeter of a right triangle. P represents Perpendicular which means the straight-line forms right angles.Īlso see: Altitude of a triangle formula Perimeter formula of Right Angled Triangle Here, H represents Hypotenuse which means the side of a right-angled triangle that is opposite the right angle.ī represents Base which means the side on which the right angle triangle stands. (Hypotenuse)² = (Base)² +(Perpendicular)² The statement of the formula is given by “The square of the hypotenuse is equal to the sum of the squares of the other two sides”. The formula of the Right-angled triangle can be explained by Pythagoras Formula. A right-angle triangle must not be an equilateral triangle because one of its angles is always 90 ° and the other two measure 45 ° each. The side which is opposite to the right angle is the hypotenuse. ![]() Triangles are three types according to their sides, they are Equilateral triangle, Isosceles triangle, and Scalene triangle.Īccording to the measures of their angles, it is of three types: Acute angled triangle, Obtuse angled triangle, and Right-angled Triangle.Ī triangle with one of its angles is a right angle that is 90° is known as the Right Angle Triangle or a Right Triangle. ![]() It has a three-sided polygon, three vertices, and three angles. A triangle is a simple closed geometrical figure which is bounded by three line segments.
