A trapezium is a shape that has four sides. It has two parallel sides, which means they are the same distance apart from each other, and two non-parallel sides, which means they are not the same distance apart from each other. One way to picture a trapezium is to think of a rectangle with the top or bottom edge slanting to one side. You might see a trapezium used in geometry or math class when you're learning about shapes or calculating area. It's also sometimes used in everyday language to describe something with a similar shape, like a building or a piece of furniture.
