A scalene triangle is a type of triangle where all three sides are of different lengths. This means that each angle in a scalene triangle is also different from the others. Scalene triangles do not have any equal sides or angles, making them unique compared to other triangle types like isosceles or equilateral triangles. In geometry, scalene triangles can be found in various shapes and sizes. They can be classified further based on their angles as acute, right, or obtuse. Understanding scalene triangles is essential in fields like architecture and engineering, where precise measurements are crucial.
