    Answer:

    In elementary geometry, the property of being perpendicular (perpendicularity) is the relationship between two lines which meet at a right angle (90 degrees). 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.

    A line is said to be perpendicular to a plane if it is perpendicular to every line in the plane that it intersects. This definition depends on the definition of perpendicularity between lines.

    Two planes in space are said to be perpendicular if the dihedral angle at which they meet is a right angle (90 degrees).

    Perpendicularity is one particular instance of the more general mathematical concept of orthogonality; perpendicularity is the orthogonality of classical geometric objects. Thus, in advanced mathematics, the word “perpendicular” is sometimes used to describe much more complicated geometric orthogonality conditions, such as that between a surface and its normal.
