A combination of a reflection and a translation (a 2-step transformation).
Is this an example of a Glide Reflection? Why or Why not?
Is this an example of a Glide Reflection? Why or Why not?
What is the function to do the TRANSLATION in this example? Explain how you came to your answer.
What is the function to do the ROTATION in this example? Explain how you came to your answer.
What does rotate mean?
What is the angle of rotation of a regular hexagon?
How does a rotation of 180 degrees around the origin change the values of coordinate (x,y) on the corrdinate graph?
What 7 letters of the alphabet have rotational symmetry?
What is the Order of Symmetry for an equilateral triangle?
A _________ is a transformation in which a figure is reflected, or flipped, over a line
A figure has __________ if a line divides the figure into two parts that are reflections of each other over the line.
_________ can be used to describe the images of figures after reflections in the axes of a coordinate plane.
This is a reflections over which axis?
This is a reflection over which axis?
Moving a shape, without rotating or flipping it. 'sliding'
Find the coordinates of the vertices of each figure after the given transformation. Translation: 2 units right and 1 unit up ( Q(0,-1), D(-2,2), V(2,4), J(3,0) )
Find the coordinates of the vertices of each figure after the given transformation. Translation: 2 units left and 1 unit down ( Q(0,-1), D(-2,2), V(2,4), J(3,0) )
Write a rule to describe the transformation.
Desribe how this is a translation
A dilation changes size, but not the ______ of a figure.
Dilations produce ______ figures.
True/False A dilation can only enlarge the size of the original figure.
The ______ factor describes how much the pre-image is reduced or enlarged.
A scale factor between 0 and 1 _____ the size of the figure.
What is Glide Reflection?
No. The Translation is correct in either direction; however, there is NO reflection.
Yes, the image was TRANSLATED from above the line and the ROTATED on the same side of the line.
(x,y) becomes (x + 5, y)
(x,y) becomes (x, -y)
What is to turn?
What is 60 degrees?
(x,y) becomes (-x,-y)

Translation: right 6, down 4
This guy is on a “slip and slide” He is sliding horizontally. Doesn’t change size or shape.
