Shapes that have only one pair of parallel sides are known as trapezoids. In a trapezoid, the two parallel sides are called the bases, and the non-parallel sides are referred to as the legs. The angles between the bases and the legs can vary, making trapezoids a versatile category of shapes.
Here are some key points about trapezoids:
- Bases: The two parallel sides of the trapezoid.
- Legs: The non-parallel sides that connect the bases.
- Height: The perpendicular distance between the two bases.
- Area: The area of a trapezoid can be calculated using the formula:
Area = (1/2) × (sum of the lengths of the bases) × height.
Trapezoids are commonly found in various real-world applications, such as in architecture, engineering, and design. Understanding their properties can be useful in solving geometric problems and in practical applications.
