Given three integers as X, Y, and Z representing the three sides of a triangle, the task is to check whether the triangle formed by the given sides is equilateral, isosceles, or scalene.. Equilateral Triangle: A triangle is said to be equilateral triangle if all the sides are equal. An isosceles triangle has two equal sides and two equal angles. However, you can imagine a right angled triangle superimposed on the purple triangle, from which the opposite, adjacent and hypotenuse sides can be determined. Scalene right triangle: This triangle is the one in which one interior angle measures 90°, while the other two measure 30° and 60°. What are the types of triangle? A scalene triangle can have a right angle, or an angle with measure 90°, but not all scalene triangles have a right angle. Reduced equations for equilateral, right and isosceles are below. If X, Y, Z are three sides of the triangle. Scalene triangle calculator diagram You can lock a side or angle and animate the other sides and angles to get the triangle dimensions you need. It is … A right triangle is a special case of a scalene triangle, in which one leg is the height when the second leg is the base, so the equation gets simplified to: area = a * b / 2.
