Properties
Translations
Rotations
Reflections
Symmetry
100
These properties of a figure are preserved (do not change) with rigid motions/transformations.
What are the angle measures and side lengths?
100
The word that describes translating.
What is sliding/shifting?
100
The word that describes rotating
What is turning?
100
This word is another way of saying reflecting
What is flipping?
100
Two types of symmetry a figure can have.
What are reflectional and rotational symmetry?
200
Three types of rigid (motions) transformations.
What are reflections, translations, and reflections?
200
The motion (direction) in this translation is
T<3, 0>
What is to the 3 units right?
200
Making both coordinates negative rotates the figure this many degrees.
What is 180o (clockwise or counterclockwise)?
200
The image and preimage have the same ________ from the line of symmetry in a reflection.
What is distance?
200
When a figure can "flip" across a line that goes through the center of the figure and map onto itself it has this type of symmetry.
What is reflectional symmetry?
300
This original figure, prior to any rigid motions/transformations, is called this.
What is the preimage?
300
This is the image coordinate pair when the preimage (1, 6) is T<-3, -1>
What is (-2, 5)?
300
The segment below has been rotated this many degrees in this direction.
What is 90o counter clockwise?
300
This coordinate changes when a figure is reflected over the x-axis.
What is the y-coordinate?
300
When an image has rotational symmetry that includes 180o, it is said to have this.
What is point symmetry?
400
A transformed figure, after any rigid motions/transformations, is called this.
What is the image?
400
This is the rule for the translation shown.
What is T<-7, 3>?
400
This is the coordinate M' after the figure below is rotated 180o clockwise.
What is (-6, -6)?
400
The figure has been reflected over this line.
What is the x-axis?
400
For a regular polygon, you do this to find the least angle of rotation for rotational symmetry.
Example: For a regular polygon with 12 sides, the least angle of rotation is. . .
Divide 360o by the number of sides.
Example: 360o/12 = 30o is the least angle of rotation
500
Which figure is the image in the following reflection:
What is the blue figure?
500
The translation below is written as.
T<-2, 2>?
500
This clockwise rotation is the same as rotating 90o counterclockwise.
What is 270o clockwise?
500
This is the coordinate A' after the figure below has been reflected over the given line.
What is (6, 1)?
500
This regular nonagon (9 sides) has rotational and reflectional symmetry.
These are the number of lines of reflectional symmetry and the angles of rotational symmetry.
What are 9 lines of reflectional symmetry and rotational symmetry of 40o, 80o, 120o, 160o, 200o, 240o, 280o, 320o?
