300
What type of rotation takes the point (x, y) to (-y, x)?
90 degrees counter clockwise or 270 clockwise
300

500
What is the coordinate of the origin?
(0,0)
500
True or false: A translated image is always similar and congruent to its pre-image.
True, translations do not change a figure's shape or size, so the image is congruent. If it is congruent, it must be similar (every shape is similar to itself with a scale factor of 1).
