Translations
What symbol shows a translation
------> (an arrow)
Another word for reflection is...
Mirrored, or flipped
What is the symbol for parallel
ll
This transformation moves a shape without moving its orientation
Translation
Corresponding means.....
The same, matching, just on another shape
What is another way to say "translate"?
Slide
Location changes in a reflection, but what else changes?
orientation
how many lines do you need to consider them to be parallel?
2 or more
This transformation spins a shape on a single point
Rotation
T or F
If two sides are corresponding, this means they are always parallel
False
A shape's location will change, but this wont...
Shape, size, orientation
What doesn't change in a reflection
size/shape
Two lines are considered parallel because they....
Go in the same direction, never intersect...etc.
This transformation flips a shape
Reflection
T or F
Corresponding sides of a refection will be on opposite sides of each other.
true
translations will always maintain_______________
Congruence
2 (across the x-axis and y-axis)
Rigid transformations always keep pairs of parallel lines because.....
Rigid transformations don't change the size or shape
This transformation keeps the same shape and size but all the points are backwards/opposite the original
Reflection
T or F
the order in which sides are labeled doesn't matter.
Which direction matches translation.....
Across the x-axis, 180 degrees clockwise, over 4 units.
over 4 units
Which direction matches reflection.....
Across the y-axis, 90 degrees clockwise, down 3 units.
across the y-axis
Shape ABCDE has 3 pairs of parallel lines. If it's rotated 90 degrees clockwise, it now has ____ pairs of parallel sides.
3
which one of these transformations is not rigid......
translation, dilation, rotation, reflection
Dilation
If a shape matches another shape, they are the same... a words for this is.....
Congruent
