The coordinates referred to either either rectangular or oblique axes are called (a) triangular axis (b)cartesian coordinate (c) parallel axis

The coordinates referred to either rectangular or oblique axes are called as Cartesian coordinates.

Option A

Explanation:

The rectangular axes are formed when two axis get joined in a perpendicular angle to each other. The oblique axes are formed when two axes do not get joined in a right angle to each other.

The axes get joined in other angles in oblique axes. The coordinates of both axes indicates the position or distances of their axes edges from the starting point or origin (0,0).

The coordinates used to represent the vertex of each axis line in a rectangular or oblique axes model is termed as Cartesian coordinates.

myth. it was once thought that animals, including cats and dogs, could only see in black and white. however, scientists have proven this to be a myth. in all animals, including humans, the perception of colour is determined by the presence of cells in the eye called cone photoreceptors.
