Question

Trapezoid FGHI is rotated using the origin as the center of rotation. The preimage and image are graphed below.

Which rotation transformed FGHI to F’G’H’I’?

a 45° counterclockwise rotation

a 45° clockwise rotation

a 90° counterclockwise rotation

a 90° clockwise rotation

Answer 1

Answer: A 45° clockwise rotation transformed FGHI to F’G’H’I’.

Explanation:

Hi, to answer this question we have to analyze the image.

The correct option is A 45° clockwise rotation.

If we put our focus in one line of the trapezoid, for example, the line FG we can see that if we compare the line FG with F'G', F'G' is positioned in a 45° angle (positive).

Feel free to ask for more if it´s necessary or if you did not understand something.

Answer 2

The rotated image if below the original image, so this shows it was rotated clockwise.

In the original image line FG is a horizontal line, if it is rotated 90 degrees, it would become a vertical line. In the rotated image line FG is at an angle, so this means it was rotated 45 degrees.

The answer is a 45 degree clockwise rotation.
