In the orthographic projection, projection lines are ____ to each

SOLUTION

Explanation:

Perspective view:

When an object is viewed from different directions and at different distances, the appearance of the object will be different. Such a view is called perspective view. 

Difference between perspective and parallel projection:

Perspective projections mimic what the human eyes see. The major difference between parallel and perspective projections is that in perspective projection, the observer is at a finite distance while in parallel projection, the observer is at infinity.

The perspective projection is most commonly used by architects.

Orthographic projection:

It is a parallel projection technique in which the parallel lines of sight are perpendicular to the projection plane.

Isometric projection:

It is a type of pictorial projection in which the dimensions along the three axes of the solid are shown in one view and in true size. It is preferred when three views of the objects are of equal importance for the accurate presentation of the object. It is one of the three types of axonometric projections named (a) trimetric projection, (b) dimetric projection, and (c) isometric projection.
