A real-life example of a scalene triangle is a roof truss as used in the building roofs on houses and buildings. Other examples include ramps and sails. A scalene triangle is defined as a triangle with no equal sides and no three angles the same.

The scalene shape is stable and strong, making it a good choice for construction. Some ramps, such as those used in a skateboarding park, are also scalene triangles. These ramps provide a stable platform from which skateboarders can launch. The sail on a sailboat is also likely to be raised in the shape of a scalene triangle, with no side of the sail being the same length as any other side.
