Height
Height is a measurement of how tall an object is from its base to its top. In the context of geometry and measurement, height is often used to describe the vertical dimension of an object.
In the case of a triangle or a rectangle, the height refers to the length of a perpendicular line drawn from the base to the opposite vertex or side. For 3-dimensional objects like a cylinder or a prism, the height is the vertical distance between the top and bottom faces.
Height is typically measured in units such as centimeters (cm), meters (m), feet (ft), or inches (in), depending on the system of measurement being used.
Understanding height is important in various fields such as architecture, engineering, and everyday measurements of objects and people.
