Answer 2

A geometric arrangement in which the position of an element is defined by two variables is known as two-dimensional space and the examples are mentioned below.

Step-by-step explanation:

• The plane was described using a Cartesian coordinate system, which is a coordinate system in which each point in a plane is uniquely specified by a pair of numerical coordinates that is, the signed distances between a point and two fixed perpendiculars directed lines, each measured in the same length unit. Each reference line is referred to as a coordinate axis or simply an axis of the system, and the origin, which is usually at an ordered pair of points, is known as the origin $(0,0)$

• The signed distances from the origin of the perpendicular projections of the point onto the two axes can alternatively be defined as coordinates.

• 2D elements are surface elements with the fundamental shapes of a triangle or quadrilateral. Examples include the 3-node triangle element, the 6-node triangular element, and a variety of additional 2D elements.
