Question

For the glide reflection where the translation is and the line of reflection is y = –x. find the coordinates of p

Answer 1

These are kinds of reflections:

Reflection across x-axis:                        (x, y) > (x, -y)

Reflection across y-axis:                        (x,y) > (-x, y)

Reflection over origin:                            (x,y) > (-x,-y)

Reflection over line y=x:                        (x,y) > (y,x)

Reflection over line y=-x:                       (x,y) > (-y,-x)
