The correct option is option: rotation 90°counterclockwise about the origin.
What is transformation?
A transformation is generally the shifting of the picture for manipulating the shape or position of a point, a line, or a geometric figure.
Transformation is a process by which the orientation or size of a given picture is changed without any effect on the shape.
A rotation is one kind of transformation in which the object rotates about a fixed point or line. The direction of rotation is clockwise or anticlockwise.
It is clear from the figure that
the triangle ∆ABC is mapped over triangle ∆A'B'C' by rotating every point 90° from 2nd quadrant to 3rd quadrant by the rotation of 90° counterclockwise about the origin.
Therefore triangle is rotated 90°counterclockwise about the origin.
