A trapezium, also known as a trapezoid in American English, has four vertices.
To understand why a trapezium has four vertices, let’s look at its definition. A trapezium is defined as a quadrilateral, meaning it is a polygon with four sides. By geometric principles, every polygon has a certain number of vertices that correspond to the number of its sides. Since a trapezium has four sides, it must also have four vertices, each vertex being the point where two sides meet.
In conclusion, no matter the specific shape or angle of the trapezium, it will always consist of four vertices.
