What is true about every rotation?
The image is smaller than the pre-image.
The image and pre-image are congruent.
The image is larger than the pre-image.
The image overlaps the pre-image.
Hello, we are given 4 facts, all of which we know must be true.
Part 1: The image is smaller than the pre image. This tells us that we are decreasing the size as we rotate.
Part 2: Cannot be true if the first one is true.
Part 3: This indicates that the image is rather being increased in size.
Part 4: Must be true if part 3 and 2 are true.
This means that 1 is the only one that can be true. Please correct me if I am misunderstanding this question.
You have misunderstood the question.
Three of the choices are wrong.
Only one is true every time.
Which one is it.
If the asker knows what a rotation is, and understands what congruent means, then they can answer themselves.
eg. Think about the hand of a clock as it rotates.
Which of those statements are nonsense and which must be true all the time?
