Who is our assistance principal?
Who is Mr. Mayne?
The word that describes translating.
Slide
The word that describes rotating
turning
This word is another way of saying reflecting
Flip or Mirror
What does this rule describe? (x, y+6)
A translation 6 units up.
The graph depicts a rigid transformation. What is the rule? Give the words and the notation.
1 unit right 2 units down: (x + 1, y - 2)
This rule describes what type of rotation?
(x,y) --> (-y,x)
90 degree counter clockwise or 270 clockwise
Adding to the x-coordinate moves a figure in this direction.
to the right
If both coordinates change signs what transformation occurred? (x,y) --> (-x,-y)
180 degree rotation
This coordinate (x or y) stays the same when a figure is reflected over the y-axis.
the y-coordinate.
Describe this transformation rule: (x, -y)
Hint: (1,2) --> (1,-2)
reflect over the x-axis
The given graph depicts a rigid transformation.
What is a reflection in the y-axis?
Who is our principal?
Who is Mr. Lodato?
If (4, 6) is translated to the left 3 and down 1, what are the new coordinates?
(1, 5)
The segment below has been rotated 90o in what direction?

counter clockwise
This coordinate changes when a figure is reflected over the x-axis.
the y-coordinate
If (1,5) becomes (3,0) what is the transformation rule?
(x + 2, y - 5)
Which is a reflection of the pre-image * over the y-axis?
What is D?
Don't Give Up!
What is "Don't ever give up!"
This is what happens to x and y values of the coordinates if a figure translates to the left and up.
subtract from the x-coordinate and add to the y-coordinate?
This is the coordinate M' after the figure below is rotated 180o clockwise.

(-6, -6)?
The figure has been reflected over this line.

the x-axis
This notation (symbol) is how we indicate the image from the pre-image
What is PRIME?
A --> A'
The given graph depicts a rigid transformation.
What is a 90-degree clockwise rotaition?
What is THE SAME? (the same shape, same angles, same side lengths)
In words, what is the translation rule for the figure to image below?

left two units, up two units
This clockwise rotation is the same as rotating 90o counterclockwise.
270o clockwise
Reflect the triangle ABC over Y-axis with side lengths AB =3 units, BC = 4 units and AC = 5 Units. After reflection, what is the length of BC?
4 units because the size of the shape does not change!
Transformations describe how a shape does what?
moves
Which is a 90-degree counterclockwise about the origin of Triangle *? 
What is figure B?
