Joanne and Christopher are designing a quilt. They start by creating a triangle shape in the lower left quadrant as shown below.
They transform it by rotating the triangle shown above 90 degrees clockwise about the origin. What does the new design look like?

1

Which figure shows the triangle below reflected over the x-axis, THEN reflected over the y-axis?

Original Figure:

After transformations:

1

Figure EFGH in the coordinate plane has vertices at (-5, 2), (-5, -2), (-1, -2), and (-1, 2).
If the figure is translated 5 units to the right and 2 units up, what are the coordinates of the
E'F'G'H' ?
