100
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
100
( x - 5, y )
What is horizontal translation of -5, no vertical translation
100

(x,y) ---> (x,-y)

What is a reflection over the x-axis

200
This is a flip over a point, line, or plane
What is a reflection
200
( -x + 6 , y - 2 )
What is a reflection over the y axis and a horizontal translation 6, vertical -2 OR a horizontal translation -6, vertical -2 and then a reflection over the y axis
200
(x,y) ---> (-x,y)
What is a reflection over the y-axis
300

This is a figure moving around a certain point in a circular motion.

What is a rotation.

300
( -x + 6 , -y +3 )
What is a 180 degree rotation, translate horizontal 6 vertical 3 translate horizontal -6 vertical -3 then a 180 degree rotation
300

What is a rotation 90 degrees CW

400
True or False : A rigid motion transformation can be a sequence of one or more transformations.
What is true
400
( y + 5 , -x -2 )
What is a 270 degree rotation CCW or 90 degree CW and translate horizontal 5, vertical -2 ) OR a horizontal translation 5, vertical 2 and then a 270 degree rotation CCW or 90 degree CW
400
(x,y) ---> (-y,x)
What is a 90 degree CCW rotation.
500

This is what it is called when two figures are the same size and shape.

What is congruent

500
(-y - 6 , -x + 3 )
What is a reflection over line y = -x , translate horizontal -6 vertical 3 OR translate horizontal 6 vertical -3 and then reflect over line y = -x
500
