If two figures are congruent, they have the same ...
size and shape
What are the coordinates of B'?

(5,5)
The figure has been reflected over this line.

What is the x-axis?

Which triangle is a Reflection of * across the y-axis?
D
How did this shape rotate?

What is clockwise 90 degrees?
The picture below shows this type of transformation.

Rotation
What is the image coordinate pair when the preimage (1, 6) is translated to the left 3 and down 1?
(-2, 5)
When a figure is translated over the y-axis, which coordinate changes?

What is (1,2)?
The rule for the given rigid transformation.
What is a Reflection across Horizontal y=1?
Name the transformation.
Dilation
What kind of rotation is performed by the rule: (x,y)--->(-x,-y)
180 degree rotation (either direction)
This notation(symbol) is how we differentiate the preimage from the image.
Prime (as in A')

(x,y)----> (x+5, y+3)
What are the coordinates of A' after the figure below has been reflected over the given line?

(6, 1)
List the series of transformations. (Make sure to pay attention to the prime symbols).
Translation down 5 and left 1
Then a reflection over the y axis
Write the rule for a 90 degree clockwise rotation.
Graph below for reference if needed

(x, y) ---> (y, -x)
Which transformations preserve congruency of a given figure?
Translation, reflection, and rotation
or "rigid transformations"
Write the rule for the below translation.
(x,y)---> (x+6,y+1)
