Reflection, Translation and Rotation

Which transformation is shown?

• Translation

• Reflection over the x-axis

• Reflection over the y-axis

• 180^o rotation

A mapping that preserves distance while moving a figure to another location using reflections, rotations or translations.

• transformation

• rigid transformation

• non-rigid transformation

• isometry

Determine where x′ would be if you translated x three units to the left and two units down.

• (-4, 6)

• (-3, 1)

• (-4, 2)

• (-2, -4)

What is translation in geometry?

• Moving a shape or object without changing its size, shape, or orientation.

• Changing the size of a shape or object without moving it.

• Reflecting a shape or object over a line without changing its size or position.

• Rotating a shape or object without changing its size or position.
