What is the sequence of transformations that maps △ABC to △A′B′C′ ?

Select from the drop-down menus to correctly identify each step.

Step 1: Choose...

Reflect across the y-axis

Reflect across the line y=x

Rotate 180 degrees about the origin

Rotate 90 degrees clockwise about the origin

Step 2: Choose...

Translate 1 unit right

Translate 2 units right

Translate 4 units down

Rotate 180 degrees about the origin

Translate 2 units right

To see this...look at A = (-1, 2)

Reflecting across the line 180 degrees about the origin reverses the signs of the coordinates = (1, -2)

Translating this two units to the right produces (3,-2) = A '

Check the other two points to see this is true....
