when two straight lines intersect with each other than vertically opposite angles will be equal .
AB and CD are two line segment and point E is called point of intersection where two lines intersect each other at a point. .angle CED and  angle AEB are also called linear pair because sum of angle CEA and angle AED is 180 degree .we can see that vertically opposite angles are equal.
