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.
You can go to the place where you got them done and ask them to take them off. Or you can use a spare fake nail and wiggle it underneath the acrylic and it should pop off. Another way you can grow your nails out and clip off the acrylic nail with nail clippers as your nail grows.
