A scalene triangle looks like a roof truss, which is used to support the roofs of houses and other buildings. Sails and ramps are also good examples. A scalene triangle is a triangle that has no three angles that are the same and no two sides that are the same.
The shape of a scalene is strong and stable, which makes it a good choice for building. Some ramps, like those used in a skateboarding park, are also scalene triangles. Skateboarders can take off from these ramps because they have a stable base. A sailboat’s sail is often raised in the shape of a scalene triangle, which means that no two sides of the sail are the same length.
