Definition

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


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 $P$.


Center of Perspective

Let $A$ and $B$ be in perspective from a point $P$.


Then $P$ is known as the center of perspective of $A$ and $B$.


Examples

Arbitrary Example
