Question

For each transformation below, state whether the lengths, angles or both are invariant.

Answer 1

How the transformations below affect length, angles or both?

• Translation - shifting same figure, lengths remain as is, angles remain as is;
• Reflection - mirroring the figure, lengths remain as is, angles remain as is;
• Rotation - rotation of the figure, lengths remain as is, angles remain as is;
• Enlargement - resizing the figure, lengths become larger, angles remain as is.
