What do you call a triangle with all sides of different lengths?

• A. Equilateral triangle
• B. Isosceles triangle
• C. Scalene triangle
• D. Right triangle

Answer: (C)

A triangle with all sides of different lengths is referred to as a scalene triangle. This classification is based on the lengths of the sides. In a scalene triangle, none of the sides are equal, and as a result, the angles opposite those sides are also different from one another. In contrast, an equilateral triangle has all three sides of equal length and all angles equal, each measuring 60 degrees. An isosceles triangle features at least two sides that are of equal length, which also means it has at least two equal angles. Finally, a right triangle is defined by having one angle that is exactly 90 degrees, and it can be isosceles or scalene depending on the lengths of its sides; the key characteristic here is the right angle. Thus, the designation of a scalene triangle clearly highlights its uniqueness in having all sides and angles distinct from one another.
