Reflection in Transformational Geometry Pre-Test

Play an AI-generated podcast conversation about this lesson

In transformational geometry, what does a reflection do to a figure?

Rotates the figure around a point

Stretches the figure horizontally

Flips the figure over a line (correct)

Compresses the figure vertically

What is the result of reflecting a triangle over the x-axis?

The triangle becomes larger

The triangle remains unchanged

The triangle flips upside down (correct)

The triangle shifts to the right

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

They switch places with the y-coordinates

They double in value

They remain unchanged

They become negative (correct)
