Or we can also give the definition of scalene triangle as “in a triangle, if no two sides are equal then it is called as a scalene triangle”. (Draw one if you ever need a right angle!) The side opposite the right angle is called the hypotenuse (side c in the figure). Along with the unequal side, the interior angles of a scalene triangle are also different. What is a Scalene Triangle? Prochainement. Scalene right-angled triangle. Right isosceles triangle: it is the triangle that has a right angle of 90º and two angles of 45º.
