The two transformations in which the orientation (the order of points as you move clockwise) does not change are translation and rotation. 2. The two transformations in which the imge has the opposite orientation from the original are reflection and glide reflection. 3. A translation by (5,12) followed by a translation by (-8,-6) is equivalent to a single translation by (-3,6). 4.
A rotation of 140 degrees followed by a rotation of 260 degrees about the same point is equivalent to a single rotation of 40 degrees about that point. 5. A reflection across a line followed by a second reflection across a parallel line that is 12 cm from the first is equivalent to a translation of 24cm. 6. A regular n-gon has n reflectional symmetries and n rotational symmetries.
