Ted draws triangle MNO in Quadrant III of the coordinate plane. He then applies 2 transformations to the triangle.

-First, the triangle is reflected across the x-axis.

-Then, the triangle is dilated by a factor of 1/3 about point M' to create triangle PQR.

Which statement is true about triangle PQR?

• Triangle PQR is congruent to triangle MNO and is in Quadrant IV.

• Triangle PQR is congruent to triangle MNO and in Quadrant II.

• Triangle PQR is similar to triangle MNO and in Quadrant IV.

• Triangle PQR is similar to triangle MNO and in Quadrant II.
