Transformations

Describe the transformations that map ABC onto A"B"C"

• translate 5 up and 1 left then reflect over y

• translate 5 down and 1 left, then reflect over y

• reflect over y=x then translate left 8

• reflect over x then rotate 90 clockwise

• reflect over the x-axis then translate 4 to the right

Transformations

What is the transformation from Triangle ABC to Triangle A''B''C''?

• Reflection x-axis, then rotation of 180 Degrees

• Reflection over y-axis, then rotation of 90 Degrees Clockwise

• Rotation of 90 Degrees Counter-Clockwise, then reflection over x-axis

• Rotation of 180 Degrees, then reflection over y-axis

• Rotation of 90 Degrees Clockwise, then reflection over y-axis
