Choose all of the statements that correctly describe the transformation rule. reflection over x-axis: (x, y) ? (? x, y) reflection over y-axis: (x, y) ? (x, ? y) rotation of 90° counter-clockwise about origin: (x, y) ? (? y, x) rotation of 180° counter-clockwise about origin: (x, y) ? (? x, ? y) rotation of 270° counter-clockwise about origin: (x, y) ? (y, ? x)

Transformations are important subjects in geometry. In this exercise, these are the correct transformation rules:

Consider the point , if you reflect this point across the x-axis you should multiply the y-coordinate by -1, so you get:

Consider the point , if you reflect this point across the y-axis you should multiply the x-coordinate by -1, so you get:

Consider the point . To rotate this point by 90° around the origin in counterclockwise direction, you can always swap the x- and y-coordinates and then multiply the new x-coordinate by -1. In a mathematical language this is as follows:

Consider the point . To rotate this point by 180° around the origin, you can flip the sign of both the x- and y-coordinates. In a mathematical language this is as follows:

Rotate a point 270° counter-clockwise about origin is the same as rotating the point 90° in clock-wise direction. So the rule is:
