Geometry

The correct statement is: All parallel lines in the 3D object remain parallel in the isometric drawing.

One of the key characteristics of isometric representation is that parallel lines in the three-dimensional object remain parallel in the two-dimensional isometric drawing. This property helps in maintaining the object's geometric relationships and makes it easier to understand the object's structure.

The other options are incorrect:

Option A: In isometric representation, the three principal axes (length, width, and height) are equally foreshortened. There is a fixed and consistent way of repr...
