What is a key feature of a scalene triangle?

A scalene triangle is defined by its property of having no equal sides or angles. This means that all three sides of the triangle are of different lengths, and consequently, all three angles are of different measurements. This characteristic is what sets scalene triangles apart from other types of triangles, such as isosceles triangles, which have two equal sides, and equilateral triangles, where all three sides and angles are equal.

In addition, a scalene triangle can have any type of angle, including acute, obtuse, or even a right angle, but the defining feature remains that it does not have any repeating side lengths or angle measures. This understanding helps to clearly distinguish scalene triangles from other triangle classifications based on their sides and angles.
