Negative sign with angle represents clockwise direction whereas positive sign represent anticlockwise direction.

So given point is 1 unit from the origin and makes$120°$ clockwise.

On reversing the direction from clockwise to anticlockwise subtract given angle from$360°$ as shown below

$360°−120°=240°$

Given point is represented as 1 unit from the origin and makes $240°$anticlockwise.

So point is$\left(1,240°\right)$

Negative sign with angle represents clockwise direction whereas positive sign represent anticlockwise direction.

So given point is 2 unit from the origin and makes$300°$ anticlockwise.

On reversing the direction from clockwise to anticlockwise subtract given angle from$360°$ as shown below

$360°−300°=60°$

Given point is represented as 2 unit from the origin and makes$60°$ clockwise.

So point is$\left(2,60°\right)$

Negative sign with angle represents clockwise direction whereas positive sign represent anticlockwise direction.

So given point is$2.5$ unit from the origin and makes$180°$ clockwise.

On reversing the direction from clockwise to anticlockwise subtract given angle from $360°$as shown below

$360°−180°=180°$

Given point is represented as $2.5$unit from the origin and makes $180°$anticlockwise.

So point is$\left(2.5,180°\right)$
