Question

Point G is rotated 90ﾟ the coordinate of the pre image point G was (7 ,-5), and its image G is at coordinate (5, 7) what is the direction of the rotation

Answer 1

Answer: The direction of the rotation is counterclockwise about the origin.

Step-by-step explanation:

• A Rotation is a transformations in which a figure is rotated about a specific point, which is the know as "Center of rotation".

• Rotation is described in terms of degrees.

• The initial figure is called "Pre-image" and the rotated figure is called "Image".

• According to Rule for 90° counterclockwise rotation about the origin:

          $(x,y)$ → $(-y, x)$

In this case, we can observe that the coordinates of the Pre-image of the Point G are:

$(7 ,-5)$

And the coordinates of its Image are:

$(5, 7)$

Then:

$(x,y)$ → $(-y, x)$

$(7 ,-5)$ → $(5, 7)$

Therefore, the direction of the rotation is counterclockwise about the origin.
