What is what does scalene mean?

Scalene is a term used in geometry to describe a triangle with three sides of different lengths. The word "scalene" comes from the Greek word "skalenos," which means "uneven" or "unequal." This distinguishes it from an equilateral triangle, which has three sides of equal length, and an isosceles triangle, which has two sides of equal length. Scalars triangles do not have any equal angles either, making it different from right triangles, acute triangles, and obtuse triangles.
