Question

give. a diagram and definition of perpendicular lines....​

Answer 1

In elementary geometry, the property of being perpendicular is the relationship between two lines which meet at a right angle. The property extends to other related geometric objects. A line is said to be perpendicular to another line if the two lines intersect at a right angle.

Answer 2

${\huge {\mathfrak {\pink {Answer :}}}}$

${\mathfrak {\red {-:Perpendicular:-}}}$

Perpendicular means "at right angles". A line meeting another at a right angle, or 90° is said to be perpendicular to it. In the figure above, the line AB is perpendicular to the line DF. If they met at some other angle we would say that AB meets DF 'obliquely'. Move the point A around and create both situations. Move the mouse carefully to get AB exactly perpendicular to DF.

${\mathfrak {\green {-:Symbols\: and \: Normal :-}}}$

➡️ AB ⊥ DF

is read as "AB is perpendicular to DF"

➡️ Another term used for the same concept is 'normal'. When line A meets line B at 90°, we say that "A is normal to B". So in the diagram above, after pressing 'reset', AB is normal to DF.
