Question

Gary said that a clockwise rotation of 90 followed by a translation 2 units to the right will make the angles coincide. What was Gary's mistake?

A. Gary did not make a mistake.
B. The translation is correct, but the rotation should have been 180.
C. The rotation is correct, but the translation should have been 2 units up.
D. The transformation should have been a reflection across the line x = 2.

Answer 1

B. The translation is correct, but the rotation should have been 180°.

Explanation:

A 90° - clockwise rotation would only turn the angle sideways.

I hope this helps you out alot, and as always, I am joyous to assist anyone at any time.

Answer 2

The Correct Option is

Option B

The translation is correct, but the rotation should have been 180°.

Explanation

When Ray HI ,and GH, is rotated by an Angle of 180°, it will be ray HI and HG, in Opposite direction originating from same point H.

Now, when we shift this angle by 2 units ,the Angle will coincide with the Angle given in the Image.
