Complete the statement: In a glide reflection, the direction of the ______ must be parallel to the line of reflection.

translation

glide reflection
reflection


Explain why a glide reflection is an isometry.


List the coordinates of the image of triangle ABC where A (-1, -3), B (-4, -1), C (-6, -4), if triangle ABC has had the glide reflection described below.
Translation: (x, y)(x + 4, y)
Reflection Line: the x-axis

Answer 1

quadrant placement

translation and reflection

never

translation

Because the preimage and image are still congruent after the glide reflection.

(-3,-3) (0,-1) (2,-4)
