Vocabulary
Translations, reflections, dilations, and rotations are 4 types of these.
What are transformations?
The shortened, "easy to remember" term for a translation.
What is slide?
The shortened, "easy to remember" term for a reflection.
What is "flip"?
Turning left or the opposite of the way the clock turns.
What is counterclockwise?
Dilation by a scale factor of greater than 1.
What is enlargement?
The point where 2 sides of a figure meet at an angle.
What is a vertex?
Find the coordinates of A' if A(2, 4) is translated by T(3, -1).
What is A'(5,3) ?
The coordinates of X' when X(-3, 1) is reflected over the x-axis.
What is X'(-3, -1)?
This angle of rotation creates the same image if it's rotated clockwise or counterclockwise.
What is a rotation of 180 degrees?
Determine the scale factor: B(2, 6) and B'(1, 3).
What is scale factor = 1/2?
The number multiplying the coordinates of a figure in a dilation.
What is a scale factor?
The term meaning "same shape, same size".
What is congruent?
The axis used as the line of reflection when a figure is reflected from Quadrant 1 to Quadrant 4.
What is the x - axis?
The number of degrees in one quadrant on the coordinate plane.
What is 90?
Find the coordinates of A' after a dilation of A (-1,4) by a scale factor of 2.
What is A' (-2, 8)?
Two figures that have the same shape and proportional sides.
What is similar?
Find the coordinates of M' when M ( -3, 4) is translated 5 units right and 2 units up.
What is M'(2 , 6)?
The axis of reflection when A (3, -4) is reflected to A' (-3, -4).
What is the y-axis?
The rotation that creates the same image as a rotation 270 degrees clockwise.
What is a rotation 90 degrees counterclockwise?
Find the coordinates of Y' when Y(12,8) are dilated by a scale factor of 1/4.
What is Y'(3, 2)?
Type of transformation that preserves distance/size (reflection, rotation, and translation).
What is a rigid transformation?
The translation rule for moving 3 units left and 2 units down.
What is (x-3, y-2)?
The original Point A is located in Quadrant 1. After a reflection over the x-axis AND then a reflection over the y-axis, in which quadrant is the final image A"?
What is Quadrant 3?
Find the coordinates of A' when A(-3, -2) is rotated clockwise 180 degrees.
What is A'(3, 2) ?
Find the coordinates of B' when B(20, 5) undergoes the a dilation of scale of 1/5.
What is B' (4, 1)?
