Dilation
What do we call the number we multiply by?
Scale Factor
When TRANSLATING left or right on a coordinate plane, what axis is affected?
x-axis
A reflection takes a figure and...
Flips it
IF we rotate clockwise we turn...
Right
What is the congruent sign?
`=
In a Dilation, what operation do we use?
Multiplication
A translation takes a figure and
Slides it
Reflect the pre-image (3,5) over the x-axis. The image is now located at what points?
(3, -5)
Moving a figure the opposite direction a clock hands moves is what?
Counterclockwise
In a dilation, the angles are congruent. True or False
True
What is Congruence?
Same shape and size
What is translation?
moves every point of a figure the same distance and direction
When we reflect over the y-axis, what stay the same?
the y-axis
(2, 3) ....if I was to rotate 180 degrees, what is the new point?
(-2,-3)
Which is the only transformation that does not stay the same when using orientation?
Reflection
The result of a transformation (NEW)
IMAGE
Translate (3, 7) using the formula (x+2, y+1), what is the new point?
(5,8)
A line over which a figure is reflected
Line of reflection
90, 180, 270 are all degrees of what?
Angles of Rotation
True or False. All congruent figures are not similar.
False
What is the only transformation that DOES NOT preserve congruence? (Not the same size and shape)
Dilation
3 left and 6 up....write the point
(-3, 6)
How is the orientation during reflection?
The image is flipped
What is rotation?
a tansformation that turns a figure
ABC is known as
the pre-image
