Answer:
vanishing point- A vanishing point is a point on the image plane of a perspective drawing where the two-dimensional perspective projections (or drawings) of mutually parallel lines in three-dimensional space appear to converge.
orthogonal- elating to or involving lines that are perpendicular or that form right angles, as in This design incorporates many orthogonal elements. Another word for this is orthographic. When lines are perpendicular, they intersect or meet to form a right angle.
picture plane- in perspective, the imaginary plane corresponding to the surface of a picture, perpendicular to the viewer's line of sight.

The second image, titled, “Nautilus, 1927” illustrates how a lack of texture enhances the illusion of an objects smooth surface on the two-dimensional print. Using rather flat lighting enhances the affect by filling in any local texture. This reduces contrast changes even more.
 
        
             
        
        
        
If people were too poor to own instruments, most people could use buckets as drums , glass jugs to make beats , their hands and feet to also make beats , and use their voices to sing. I tried my best , hope this helped!
