Consider the square, R
S
Q
T
Which two transformations carry the square onto itself?
O a reflection across the line passing through point Q and point S
O a reflection across line RQ
O a rotation 90° clockwise about point Q
O a rotation 180 clockwise about point R
O a rotation 360clockwise about point T

The question is kind of confusing. if it's asking how many variations of answers can you give. then do 4^5 for your answer.this would be something like the first question could be a and the 2nd c or first b next c etc. if you can, ask the teacher for a better confirmation of what it's asking. if i'm assuming correctly what it's asking, it's 625 different variations.
