A line of symmetry is also a line of

Accepted Answer

reflection

Answer

isometry

Answer

translation

Answer

rotation

Question 19

A reflection is an isometry

Accepted Answer

The statement is true because neither the shape nor the size of a figure is changed in a reflection

Answer

The statement is true because the preimage and image have opposite orientations
