Describe a translation
Moving all points in the figure the same distance and the same direction.
What happens to a coordinate when reflected over the x-axis?
Changes the sign of the y value.
Point D(-11, 2) is transformed and ends up at (-6, 4). What type of transformation ocured?
Translation
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)
Solve for x:
3x + 5 = 20
What is x = 5?
Adding to the x-coordinate moves a figure in this direction.
to the right
This value stays the same when a figure is reflected over the y-axis.
the y-value
Dilation
The given graph depicts a rigid transformation.
What is a reflection in the y-axis?
This type of relationship has a graph that is a straight line and passes through the origin.
What is a proportional relationship?
If (1, 6) is translated to the left 3 and down 1, what are the new coordinates?
(-2, 5)
Point (28, -37) is reflected over the y axis, then reflected over the x-axis. What is the coordinate of the Image?
(-28, 37)
If (1,5) becomes (3,0) what did we do to both the x and y value?
(x + 2, y - 5)
The given graph depict multiple transformations of the pre-image *. This image depicts a Reflection of * across the y-axis.
What is D?
The square root of 729.
What is 27?
Point K(-9, 13) is translated 9 units up and 13 units left. What is the coordinate of the image?
(0, 0)
The figure has been reflected over this line.

the x-axis
Define a reflection.
A reflection is a flip across the x or y axis
The given graph depicts a rigid transformation.
What is a 90-degree clockwise rotaition?
If a right triangle has legs of 7 cm and 24 cm, this is the length of the hypotenuse.
25 cm
In words, what is the translation rule for the figure to image below?

left two units, up two units
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.
Name the four types of Transformations.
Translation, reflections, rotations, dilations
The given graph shows rigid transformations of the pre-image . Triangle * will have a Rotations of 90-degrees counterclockwise about the origin. Where will the new figure be? 
What is figure B?
