100
A transformation in which a graph or geometric figure slides to another location
What is translation?
100
a figure that is translated 3 units left that starts at (0,0)
What is (-3,0)
100
What happens in a reflection across the y axis?
What is (x,y) becomes (-x, y)
100
This angle of rotation creates the same image if it's rotated clockwise or counterclockwise. Also (x,y) turns into (-x,-y)
What is a rotation of 180 degrees?
200
Operations that alter the form of a figure. Examples: translations, reflections, and rotations.
What is transformations?
200
Find the coordinates of A' if segment AB with A(2, 4) and B(-1, 1) is translated by (2, -5)
What is A'(4, -1)?
200
The coordinates of X' when XY with X(-3, 1) and Y(-1, 4) is reflected over the x-axis.
What is X'(-3, -1)?
200
The rotation of 270 degrees clockwise.
What is (x,y) becomes (-y, x)
300
The two axis' where transformations occur
What is the x and y axis?
300
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 X'(-5, 4), Y'(-2, -1), and Z'(-1, 1)?
300
What happens in a reflection across the x-axis?
What is (x,y) becomes (x,-y)
300
A rotation clockwise of 90 degrees.
What is (x, y)-->(y, -x)
400
A transformation in which a plane figure turns around a fixed center point.
What is rotation?
400
Find the coordinates of M' and N' when MN with M(-4, -1) and N(-3, -3) is translated 5 units right and 2 units up.
What is M'(1, 1) and N'(2, -1)?
400
The line of reflection over x axis when A(-2, 0), B(1, 3), and C(3, -4)
What is A' (-2,0) B' (1,-3) C 3,4)
400
This angle of rotation maps (x, y)-->(-y, x).
What is rotation 270 degrees clockwise or 90 degrees counterclockwise?
