How do you get from the red triangle to the orange triangle?

• reflection over the y-axis and then the x-axis

• rotate 270 degrees and reflect over y = 2

• reflection over the y-axis and translate up 7

• rotate 180 degrees and reflect over y = 2

• translate up 7, translate right 6, and then reflect over the x-axis
