Front

Reflecting over the y-axis changes the ____-_____________.

Back

x-coordinate

Front

Which transformation describes a movement without changing the shape or size of a figure?

Back

Translation (Slide)

Front

What is the result of rotating a figure 90 degrees clockwise around the origin?

Back

The figure's position changes, but its shape and size remain the same.

Front

What is the term for a transformation that flips a figure over a line?

Back

Reflection

Front

What is the effect of a translation on a geometric figure?

Back

It moves the figure to a different location without altering its shape or size.

Front

What is the term for a transformation that enlarges or reduces a figure?

Back

Dilation

Front

Describe the sequence of transformations: Reflect across the x-axis and then rotate -90 degrees cw around the origin.

Back

The figure is first flipped over the x-axis and then rotated clockwise.

Front

What is the result of reflecting a figure over the y-axis?

Back

The x-coordinates of the points of the figure change sign.

Front

What does a 90° counter-clockwise rotation about the origin do to a point (x, y)?

Back

It transforms the point to (-y, x).

Front

What is the effect of a reflection over the x-axis on the coordinates of a point (x, y)?

Back

The point becomes (x, -y).
