Descriptive Geometry is a way of drawing shapes on paper in a way that uses measurements to show how the shapes look in 3-dimensional space. It helps us to understand how shapes change when viewed from different angles in three-dimensional space. To do it, you take measurements of the object, like height, length, and width, and then you draw it on the paper with all the measurements in the right places and angles. That way you can see how the object looks from different angles, like from above, from the side, and from the front.
