Translations
What is another name for a translation
Slide
What is another name for a reflection
flip
What is another name for a rotation
turn
What does congruent mean?
same size and shape
name three types of transformation
translation, rotation, reflection
Which direction does the x axis move
left and right
when we reflect over the x axis which coordinate changes?
the y coordinate
how many turns do I make when I rotate a figure 90 degrees
1 turn
Are a square and pentagon congruent
No, they are not the same size or shape
True or False
Side lengths and angle measures stay the same when I perform a transformation
True
Which direction and how many units are you moving on the y axis
( x-2)( y+6)
6 units up
True or False
when we reflect over the y axis, the y axis changes?
False
the following rule was applied when rotating a figure
(x,y)- (-x,-y)
How many degrees did I rotate my figure
180 degrees
All rigid transformation create
congruent figures
Translations, Reflections and rotations are
rigid transformations
Describe the translation
( x-4)(y-2)
4 units left, 2 units down
the pre-image has the point ( 3,-2)
It is reflected over the x axis. What is the new point
(3,2)
Using the rule
(x,y)- (y,-x)
the point ( 4,6) will be where when rotated 90 degrees
( 6,-4)
the point ( 4,2) is reflected over the x axis and translated up 4. What is the new point.
( -4,6)
what transformation was done
( x-3)(y+2)
translation 3 units left, 2 units up
Give me the mapping notion for the following
4 units right, 8 units up
( x+4)(y+8)
the pre -image has a point (7,2)
It is reflected across the y axis. What is the new point?
(-7,2)
rotate point (4,-6) 270 degrees.
what is the new point
( 6,4)
the point (3,7) is rotated 180 degrees and reflected over the y axis. What is the new point
(3,-7)
what transformation happened
( 4,2)- (2,-4)
rotate 90 degrees clockwise
