Front

What is the rule for rotation of 90 degrees clockwise?

Back

RULE (x, y) --> (y, -x)

Front

Write a rule for the translation that moves a point 2 units left and 9 units up.

Back

RULE (x, y) --> (x - 2, y + 9)

Front

Which is a rule for a reflection over the x-axis?

Back

RULE (x, y) --> (x, -y)

Front

What is the rule for rotation of 270 degrees counterclockwise?

Back

RULE (x, y) --> (y, -x)

Front

Define reflection in geometry.

Back

Reflection is a transformation that flips a figure over a line, creating a mirror image.

Front

What is the general rule for translation in the coordinate plane?

Back

RULE (x, y) --> (x + a, y + b), where a and b are the horizontal and vertical shifts.

Front

What happens to the coordinates of a point during a 180-degree rotation?

Back

RULE (x, y) --> (-x, -y)

Front

Explain the concept of rotation in geometry.

Back

Rotation is a transformation that turns a figure around a fixed point, called the center of rotation.

Front

What is the rule for a reflection over the line y = x?

Back

RULE (x, y) --> (y, x)
