A graph vertex in a graph is said to be an odd node if its vertex degree is odd, i.e., if the number of edges the vertex is connected to is odd. Since we are ...
Perpendicular lines - Geometry and Coordinate Geometry
"How can you determine if two lines are perpendicular?"
This is what I understand out of it By definition, perpendicular lines intersect each other at 90 degree angle.
In co-ordinate geometry, product of their slopes is -1.
