What is the sequence of transformations?

• Reflect over the y then reflect over the x

• Reflect over the x then reflect over the y

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

• It changes the size of the figure.

• It changes the orientation of the figure.

• It moves the figure without changing its shape or size.

• It flips the figure over a line.

Which of the following transformations is non-rigid?

• Translation

• Rotation

• Reflection

• Dilation

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

• The figure is flipped over the x-axis.

• The figure is flipped over the y-axis.

• The figure is moved to a new position without changing its orientation.

• The figure is turned 90 degrees to the right.

If a figure is reflected over the y-axis, what happens to the x-coordinates of its points?

• They remain the same.

• They are multiplied by -1.

• They are divided by 2.

• They are squared.

Which sequence of transformations is equivalent to a single translation?

• Two reflections over parallel lines

• Two rotations of 180 degrees

• A reflection followed by a rotation

• A dilation followed by a reflection
