Translations
Label and state the prime image of A (1, 4) after a translation 5 units left and 4 units up?
A'(-4, 8)
What is the new image of (5, 3) if you rotate the point 90 degrees counterclockwise? Hint: (x,y) ==> (-y, x)
(-3, 5)
True or False: Reflections preserve size and orientation.
False - orientation is not preserved under a reflection.
Translations, reflections, and rotations produce a figure that is __________ to the original figure.
congruent
What is the definition of an image?
The output of a transformation
Translate L (-3, -2) 1 unit right and 3 units up.
L'(-2, 1)
True or False: Rotating a figure 90 degrees is NOT the same as rotating a figure -270 degrees.
False - rotating a figure 90 degrees IS the same as rotating a figure -270 degrees.
What is the new ordered pair of H(-7, 9) if you reflect it over the x-axis?

L
The input of a Transformation is called...
the preimage
What is the algebraic translation if the points are going from A(-3, -4) to A'(3, -4)?
Hint: (x, y) ==> (___, ___)
