How many degrees must you rotate a line so that its image is parallel to itself?
180
200
If you reflect objects, in what scenarios are they mapped onto themselves?
When the object is on the line of reflection.
200
Objects are moved along ____________ in translations.
Vector
200
Basic Rigid motions preserve....
angle measures and segment lengths
200
Name this vector -------------------> D C

To rotate positive degrees you go in which direction?
Counterclockwise
300
If a point, P, is reflected and you draw a line to connect the point and its image, what size are the lengths of the segments and why?
They are equal because the line of reflection bisects P and P'

Basic Rigid Motions m__________________________________
map lines to lines, angles to angles, etc
