1 sided symmetry
When a figure has the SAME orientation as its reflection
2 sided symmetry
When a figure has an orientation OPPOSITE that of its reflection
Translation
A transformation that slides two points over
Rotational
Turns a figure about a fixed point (the center of rotation) a certain amount(the angle of rotation) in a given direction.
Reflection
A transformation that flips a figure over a line, creating a mirror image.
Glide reflection
is a transformation that combines a translation and a reflection, sliding a figure along a line and then reflecting it over that line.
Translation mathematically
F (x ,y) = F( x + h , y +k) h= L&R K= up&down
Tessellation
A pattern of shapes that fit perfectly together without any gaps or overlaps
