Final answer:
Yes, the composition Ro90° or y is equivalent to the composition rgo R0,90º.
Step-by-step explanation:
Yes, the composition Ro90° or y is equivalent to the composition rgo R0,90º.
In both cases, the angles represent rotations and can be expressed as both a positive or negative angle. The angle Ro90° or y represents a rotation of 90 degrees counterclockwise, while the angle rgo R0,90º represents a rotation of 90 degrees clockwise. Since rotations in opposite directions cancel each other out, a rotation of -90 degrees clockwise is equivalent to a rotation of 90 degrees counterclockwise.
For example, if you rotate an object 90 degrees counterclockwise and then 90 degrees clockwise, the net rotation will be 0 degrees.
