what is a slide
Translation
Translate point (-4, -4) x + 3, y + 4
(-1, 0)
Reflect H(3, -4) over the y-axis (no graph)
(-3, -4)
When you dilate a figure, the shape stays the same size
False
X(3, -1) Rotate 180 degrees clockwise (No graph)
(-3, 1)
What is a general term for four specific ways to manipulate the shape of a point, a line, or shape?
Transformation
Translate B (3,1) x-2, y + 1
(1, 2)
When reflecting a point over the x-axis, which coordinate remains the same
x-coordinate
T(5,5) scale factor of 2
(10, 10)
M(1,4) Rotate 90 degrees clockwise (No graph)
(4, -1)
What is the original figure called
preimage
If point J(-3,4) is moved two units right and 5 units down, what are the coordinates of point J'
(-1, -1)
Reflect points (-6, -3) over the x-axis than the y-axis.
(6, 3)
J(0, -4) scale factor of 1/4
(0, -1)
rotate the following points 270 degrees A=(3, 6) B=(5, 5)
A'=(6, -3) B'=(5, -5)
What is a mirror image
reflection
If point k(1,3) is moved two units right and 5 units down, what are the coordinates of point K'
(3, -2)
Reflect J(1,1) over the y-axis and point R (5,5) over the y-axis.
J'(-1,1) R' (-5,5)
When what number is exceeded for the scale factor does the dilation become and enlargement?
When the scale factor is above 1.
What would the new point be if it is rotated 90 degrees, then reflected across the x-axis?
A=(1,2)
A'' (-2, -1)
What is a turn
rotation
If point L(-4,1) is moved two units right and 5 units down, what are the coordinates of point L'
(-2, -4)
reflect the following points across the y=x line A=(-2, 3) B=(4, -1) C=(3, 6)
A'=(3, -2) B'=(-1, 4) C'=(6, 3)
dilate the following points by a scale factor of 1.5 A=(5, 1) B=(9, 6) C=(1, 1)
A'=(7.5, 1.5) B'=(13.5, 9) C'=(1.5, 1.5)
