Perpendicular lines are the two lines that intersect each other at right angle or 90 degrees. Visit BYJU'S to learn the symbol, properties, difference between parallel and perpendicular lines in detail.
If two lines intersect to form a linear pair of congruent angles, then the lines are perpendicular. Proof: When two adjacent angles form a linear pair, their non-shared sides form a straight line ( m ).
Two distinct lines intersecting each other at $90^{\circ}$ or at a right angle are called perpendicular lines. Example : Here, AB is perpendicular to XY because AB and XY intersect each other at $90^{\circ}$.
We say that a line is perpendicular to another line if the two lines meet at an angle of 90 °. Let us understand the concept of perpendicular lines, the perpendicular sign, the difference between parallel and perpendicular lines, along with some perpendicular lines examples.
Perpendicular lines, rays, and line segments are lines or parts of lines that meet or cross at right angles. If lines l and m are perpendicular to each other, we can write l⊥m where "⊥" is the symbol for perpendicular.
If two lines are perpendicular to the same line, then they both are parallel to each other and never intersect. Two perpendicular lines can be used to make one straight angle. A triangle is said to be a right isosceles triangle if apart from two sides being equal, one of the angles of the triangle is a right angle, i.e. 90 o .

A perpendicular bisector is a line (or segment or ray) that is perpendicular to a side of the triangle and also bisects that side of the triangle by intersecting the side at its midpoint. The perpendicular bisector may, or may NOT, pass through the vertex of the triangle.
