In Euclidean plane geometry, a rectangle is a quadrilateral with four right angles. It can also be
defined as: an
equiangular quadrilateral, since equiangular means that all of its angles are equal; or a parallelogram
containing
a
right angle.A rectangle with four sides of equal length is a square.

A circle is a shape consisting of all points in a plane that are at a given distance from a given
point, the centre.
Equivalently, it is the curve traced out by a point that moves in a plane so that its distance from a
given point is
constant.

In geometry, a line segment is a part of a straight line that is bounded by two distinct end
points, and contains every
point on the line that is between its endpoints.

A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in
geometry. A triangle with
vertices A, B, and C is denoted triangle ABC. In Euclidean geometry, any three points, when
non-collinear, determine a
unique triangle and simultaneously, a unique plane.
