An exact location. It has no size, only position.
a long, narrow mark or band.
a flat surface on which a straight line joining any two points.
Two or more lines that meet at a point are called intersecting lines.
In geometry, parallel lines are lines in a plane which do not meet; that is, two lines in a plane that do not intersect or touch at any point are said to be parallel.
n three-dimensional geometry, skew lines are two lines that do not intersect and are not parallel. A simple example of a pair of skew linesis the pair of lines through opposite edges of a regular tetrahedron.
a line perpendicular to a surface or to another line
parallel to or in the plane of the horizon or a baseline.
An angle that measures less than ninety degrees but more than zero degrees.
an angle that measures more than 90 degrees but less than 180 degrees.
an angle of 90°, as in a corner of a square or at the intersection of two perpendicular straight lines.
a plane figure with four equal straight sides and four right angles.
a plane figure with four straight sides and four right angles, especially one with unequal adjacent sides, in contrast to a square.
a quadrilateral with only one pair of parallel sides.
a parallelogram with opposite equal acute angles, opposite equal obtuse angles, and four equal sides.
a four-sided plane rectilinear figure with opposite sides parallel.
a plane figure with five straight sides and five angles.
a plane figure with six straight sides and angles.
a plane figure with eight straight sides and eight angles.
a plane figure with ten straight sides and angles
a solid or hollow object that tapers from a circular or roughly circular base to a point.
a round solid figure, or its surface, with every point on its surface equidistant from its center.
a solid geometric figure whose two end faces are similar, equal, and parallel rectilinear figures, and whose sides are parallelograms
an object, shape, or arrangement in the form of a pyramid
a symmetrical three-dimensional shape, either solid or hollow, contained by six equal squares
