Which transformations were used to create congruent triangle E’F’G from triangle EFG? 1. reflection across the y-axis and a translation
2. rotation of 180 degrees about the origin and a reflection across the y-axis
3. rotation of 90 degrees clockwise about the origin and a reflection across the x-axis
4. reflection across the x-axis and a translation

In this problem it decreased 20%

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.
