What is translation?
A transformation in which a graph or geometric figure is picked up and moved to another location without any change in size or orientation.
What is <-3, 0>?
What is <-3, 0>?The vector notation for a figure that is translated 3 units left.
What is x=0?
The equation for the line of reflection if a figure is reflected over the y-axis.
What is a rotation of 180 degrees?
this angle of rotation creates the same image if it's rotated clockwise or counterclockwise.
What is transformations?
Operations that alter the form of a figure. Examples: translations, reflections, dilations, and rotations.
If A is 2,4 and it is translated by <2, -5> what is A'
A'(4, -1)
The coordinates of X' when XY with X(-3, 1) and Y(-1, 4) is reflected over the x-axis.
X'(-3, -1)?
What is a rotation 90 degrees counterclockwise?
A rotation to next location to the left
pre-image
Is the original Image
X'(-5, 4), Y'(-2, -1), and Z'(-1, 1)
Find the coordinates of X', Y', and Z' when triangle XYZ with X(0,3), Y(3, -2), and Z(4,0) is translated by <-5, 1>.

What is rotation 270 degrees clockwise or 90 degrees counterclockwise?
This angle of rotation maps (x, y)-->(-y, x).
Rigid Motion ?
If the shape and the size of a figure remains the same in transformation
What is (x, y)-->(x+3, y-4)?
What is (x, y)-->(x+3, y-4)?It means that the figure will move to the right and 4 down
