A segment joining two nonconsecutive vertices.

A pair of legs at the trot, such as the right front and the left hind. When posting, the rider sits as the inside hind hits the ground or "raise and fall with the (front) leg on the wall." Riding across the diagonal is a maneuver from one corner of an arena to another through the center.

A segment connecting two non-adjacent vertices of a polygon diagonal

Device used with a refractor or catadioptric that places the eyepiece at a more comfortable viewing angle. Consists of a mirror within an angled housing. Common angles are 45 degrees for terrestrial viewing, and 90 degrees for astronomical viewing.

Reference to the horse moving its leg in diagonal pairs whilst trotting.

A line on the chess board from North East to South West or from North West to South East, as traversed by bishops and queens. The diagonals from corner to corner are the LONG DIAGONALS.

A line segment that connects two vertices in a polygon.

The diagonal of a square or rectangle, or its cross corner length.

45 degrees out from the center of the Line of Dance (direction)

a line segment joining any two vertices of a polygon not already joined

A line segment lying entirely inside polygon and joining two non-consecutive vertices pi and pj

A line segment connecting non-adjacent vertices of a polygon. Note: An n-gon has diagonals.

(geometry) a straight line connecting any two vertices of a polygon that are not adjacent

a line or cut across a fabric that is not at right angles to a side of the fabric

at an angle; especially connecting two nonadjacent corners of a plane figure or any two corners of a solid that are not in the same face; "a diagonal line across the page"

a line segment that connects two non-adjacent vertices of P and has no intersection with the exterior of P

a line segment that joins two nonadjacent vertices in a polygon

For a polygon in the plane, any line segment joining non-adjacent vertices. For a polyhedron in space, a line segment joining two vertices not in the same face.

A method of measuring and describing the size of a screen or a projected image - from one corner to the diagonally opposite corner. A 9ft high, 12ft wide screen has a diagonal of 15ft.

Line segment joining two non-adjacent vertices in a polygon or two vertices of a polyhedron not on the same surface.

A line that joins two opposite corners of a four-sided figure.

comes from the Greek roots dia( to pass through or join) + gonus [angle] and describes the line segment which passes from the vertex of one angle to another in a polygon. The word diagonal was probably first used in a geometric sense by Heron of Alexandria.

This is the curve defined by intersecting a plane diagonally through the bilge area of the hull geometry. The curve can be seen in the profile or plan views. The diagonal plane is defined by two values: its intersection height (Z-value) on centerline and the heel angle of the plane.

A segment with two nonadjacent vertices of a polygon as its endpoints.

A line of squares of the same colour, along which a queen or bishop can move.

A segment joining two non-consecutive vertices of a polygon.

a straight line joining corners of a square or rectangle.

A diagonal is a line that joins two non-consecutive vertices of a polygon.

Reaching from corner to opposite corner at an angle.

Any action (pass, kick or run) that moves corner-to-corner with respect to the field of play. The player doesn't have to use all the space between the corners, which are simply a reference to a diagonal.

A line segment joining two non-adjacent vertices of a polygon.

A straight line which is not horizontal or vertical. The use of strong diagonal elements in composition is common. See Composition and Design Forum.

1. A line, in a rectangular figure, running at angle from the middle of an angle to the middle of an opposite angle. 2. Moving or extending at a 45-degree angle. 3. Slanted markings or lines across a surface.

A diagonal can refer to a line joining two nonadjacent vertices of a polygon or polyhedron, or in some contexts, any upward or downward sloping line. The word "diagonal" was originally from the Greek Î´Î¹Î±Î³Ï‰Î½Î¹Î¿Ï‚ (diagonios), used by both StraboStrabo, Geography 2.1.36-37 and EuclidEuclid, Elements book 11, proposition 28 to refer to a line connecting two vertices of a rhombus or cuboid,Euclid, Elements book 11, proposition 38 and is formed from dia- ("through", "across") and gonia ("angle", related to gony "knee."), later adopted into Latin as diagonus ("slanting line").
