Final answer:
A triangle with three unequal sides is called a Scalene Triangle. In such a triangle, not only the sides but all the angles are also different. A triangle with sides of lengths 3cm, 4cm, and 5cm is an example of scalene triangle.
Step-by-step explanation:
A triangle where all sides are unequal is called a Scalene Triangle. In a scalene triangle, not only are all the sides different, but all the angles are also different. For example, a triangle with sides of lengths 3cm, 4cm, and 5cm is a scalene triangle. Also, the angles within aren't the same - none of them are 60 degrees, as you'd see in an equilateral triangle. It's the diversity of lengths and internal angles that distinguishes a scalene triangle.
