gothic architecture,
gothic a style of architecture developed in northern France that spread throughout Europe between the 12th and 16th centuries; characterized by slender vertical piers and counterbalancing buttresses and by vaulting and pointed arches
perpendicular -
a straight line at right angles to another line
straight line a line traced by a point traveling in a constant direction; a line of zero curvature; "the shortest distance between two points is a straight line"
perpendicular -
a cord from which a metal weight is suspended pointing directly to the earth's center of gravity; used to determine the vertical from a given point
perpendicular -
intersecting at or forming right angles; "the axes are perpendicular to each other"
oblique slanting or inclined in direction or course or position--neither parallel nor perpendicular nor right-angled; "the oblique rays of the winter sun"; "acute and obtuse angles are oblique angles"; "the axis of an oblique cone is not perpendicular to its base"
parallel being everywhere equidistant and not intersecting; "parallel lines never converge"; "concentric circles are parallel"; "dancers in two parallel rows"
normal conforming with or constituting a norm or standard or level or type or social norm; not abnormal; "serve wine at normal room temperature"; "normal diplomatic relations"; "normal working hours"; "normal word order"; "normal curiosity"; "the normal course of events"
rectangular,
orthogonal having four right angles; "a rectangular figure twice as long as it is wide"
perpendicular -
extremely steep; "the great perpendicular face of the cliff"
steep having a sharp inclination; "the steep attic stairs"; "steep cliffs"
perpendicular -
at right angles to the plane of the horizon or a base line; "a vertical camera angle"; "the monument consists of two vertical pillars supporting a horizontal slab"; "measure the perpendicular height"
(or a line and a plane), are considered perpendicular to each other if they form congruent adjacent angles (a T-shape). The term may be used as a noun or adjective. Thus, referring to Figure 1, the line AB is the perpendicular to CD through the point B.
