Definitions
This is a movement of all points on a figure in a fixed distance “a” units in the x-direction and “b” units in the y-direction.
What is a translation
(3, 4) after a reflection over the y-axis
What is (-3, 4)?
(x,y) ---> (x,y)
What is a 360 degree rotation
This is a flip over a point, line, or plane
What is a reflection
(-6, 7) after a 180 degree rotation
What is (6, -7)?
(x,y) ---> (-x,y)
What is a reflection over the y-axis
This is two rays that share a common starting point.
What is an angle
(-5, 6) after a reflection over the line y = -x.
What is (-6, 5)?
(x,y) ---> (y,x)
What is a reflection over line y = x
True or False : A rigid motion transformation can be a sequence of one or more transformations.
What is true
(9, -6) after the translation (x - 5, y + 6)
What is (4, 0)?
(x,y) ---> (-y,x)
What is a 90 degree CCW rotation.
Things preserved in a rigid motion
What is the segment length and angle measures?
(-4, 3) after a rotation 90 degrees ccw and a reflection over the x-axis
What is (-3, 4)?
(x,y) ---> (-y,-x)
What is a reflection over line y=-x
