#### Answer

The origin in the rectangular coordinate system coincides with the pole in polar coordinates. The positive x-axis in rectangular coordinates coincides with the polar axis in polar coordinates.

#### Work Step by Step

The two different ways of locating a point in a plane are the rectangular coordinate system and polar coordinate system.
In the polar coordinate system, each point on a plane is determined by a distance from a reference point and an angle from the reference direction. It is represented by $\left( r,\theta \right)$, where r denotes the distance from the reference point and $\theta $ denotes the angle that it makes with the reference direction.
But in the rectangular coordinate system, each point in a plane is determined by a pair of coordinates and represented in the form of $\left( x,y \right)$.
So, in the rectangular coordinate system, the origin coincides with the origin in the polar system this coincides with the pole.
So, both representations are similar but their nature will vary.
