Rigid Transformations Math

What is the result of reflecting a point (x, y) across the x-axis?

• (x, y)

• (-x, y)

• (x, -y)

• (-x, -y)

What is the transformation that moves a figure without changing its orientation or size?

• Rotation

• Reflection

• Translation

• Dilation

What is the effect of a dilation with a scale factor less than 1?

• The figure reduces.

• 90 degrees

• 180 degrees

• 270 degrees

• 360 degrees

What is the result of a 90-degree counterclockwise rotation of a point (x, y)?

• (x, y)

• (y, -x)

• (-y, x)

• (x, -y)
