Definition

Let $A$ and $B$ be plane geometric figures.

Perspective from Point

Let $A$ and $B$ be such that their points are in one-to-one correspondence such that the lines joining pairs of corresponding points pass through a single point $P$.

Then $A$ and $B$ are in perspective from a point, and that point is $P$.


Perspective from Line

Let $A$ and $B$ be such that their points are in one-to-one correspondence such that the lines joining pairs of corresponding points lie on the same straight line $L$.

Then $A$ and $B$ are in perspective from a line, and that line is $L$.
