Question

Rectangular coordinate system is also known as:
(A) Space coordinate system
(B) Polar coordinate system
(C) Cartesian coordinate system
(D) Planar coordinate system

Answer 1

Hint: To locate the position of a point in a plane using two perpendicular lines, the coordinate system is used. Points are represented in two-dimensional coordinates $ (x,y) $ with respect to the x- and y- axes.

Complete Step-by-Step Solution
A space coordinate system in astronomy is a system for specifying the positions of satellites, planets, stars, galaxies, and other celestial objects relative to the physical reference points available to the located observer. Coordinate systems, if the distance of the object is unknown or trivial, can specify the position of an object in three-dimensional space or simply plot its direction on a celestial sphere.
The polar coordinate system is a two-dimensional coordinate system in which the distance from the reference point and the angle from the reference direction are determined for each point on the plane. The pole is called the reference point and the polar axis is the ray from the pole in the reference direction.
A Cartesian coordinate system is a coordinate system that uniquely specifies each point in a plane by means of a set of numerical coordinates, which are the distances signed from two fixed perpendicular oriented lines to the point measured in the same unit of length. Each reference line is referred to as a coordinate axis or just the system axis, and the point where it meets is its origin at the ordered pair $ (0,0) $ . It is also possible to define the coordinates as the positions of the point's perpendicular projections on the two axes, expressed as signed distances from the origin.
Suppose a ruler and pencil are taken, the map is divided into squares, and each square is labelled. Then, in each square, you could write down the names of all the streets and alphabetize your list. You'd look up at neighbouring places to find the intersection of a place and see what square (or squares) it lies in. For other locations, you'd do the same. The part of the map where you'll find the intersection is the square they have in common. Since this method will work on the map for any street or intersection, it really is a reference system for location.
Hence, the correct option is (C).

Note
In addition, the axes divide the plane into four sections, and these four sections are called quadrants (one-fourth part). Therefore, we have four quadrants numbered I, II, III and IV anti-clockwise. A plane consists of axes and quadrants. We call the plane, the Cartesian Plane, or the Coordinate Plane, or the x-y plane. The axes are called the axes of the coordinates.
