Translations
Label and state the prime image of A(1, 4) after a translation 4 units up?

Which way is counter-clockwise?
left
True or False: Reflections can only be flipped in one direction.
False - Reflections can be flipped top to bottom or left to right.
True or False: A dilation makes congruent figures.
True - A dilation makes similar figures.
What is the definition of an image?
Shape after transformation has been performed
Translate L(-3, -2) A(0, -1) D(3, -2) 1 unit right and 3 units up.
L'(-2, 1) A'(1, 2) D'(4, 1)
True or False: Rotating a figure 90 clockwise degrees is NOT the same as rotating a figure 270 counterclockwise degrees.
False - rotating a figure 90 clockwise degrees IS the same as rotating a figure 270 counterclockwise degrees.
