Perpendicular Lines
When two lines intersect and the angle between them is a right angle, then the lines are said to be
For eg- If a line AB is perpendicular to CD, we write AB
If AB ⊥ CD, then should we say that CD ⊥ AB also?
We can find plenty of examples from things around us for perpendicular lines (or line segments). Take the corner of a rectangular table. The English alphabet 'T' is one.
Consider the edges of a post card. The edges are
Let AB be a line segment. Mark its mid point as O. Let OP be a line perpendicular to AB through O.
Since, O is the mid-point of AB, we can say that OP bisects AB i.e. divides AB into two equal parts while also being perpendicular to AB.
Therefore, OP is the perpendicular bisector of AB.
