Glide Reflection |
#1 |
A combination of a reflection and a translation (a 2-step transformation). |
What is Glide Reflection? |
#2 |
Is this an example of a Glide Reflection? Why or Why not? |
No. The Translation is correct in either direction; however, there is NO reflection. |
#3 |
Is this an example of a Glide Reflection? Why or Why not? |
Yes, the image was TRANSLATED from above the line and the ROTATED on the same side of the line. |
#4 |
What is the function to do the TRANSLATION in this example? Explain how you came to your answer. |
(x,y) becomes (x + 5, y) |
#5 |
What is the function to do the ROTATION in this example? Explain how you came to your answer. |
(x,y) becomes (x, -y) |
Reflection (line symmetry) |
#1 |
A _________ is a transformation in which a figure is reflected, or flipped, over a line |
What is reflection? |
#2 |
A figure has __________ if a line divides the figure into two parts that are reflections of each other over the line. |
What is line symmetry? |
#3 |
_________ can be used to describe the images of figures after reflections in the axes of a coordinate plane. |
What is coordinate notation? |
#4 |
This is a reflections over which axis? |
What is y-axis? |
#5 |
This is a reflection over which axis? |
What is x-axis? |
Translation |
#1 |
Moving a shape, without rotating or flipping it. 'sliding' |
What is translation? |
#2 |
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) ) |
Q (2,0), D (0,3), V (4,5), J (5,1) |
#3 |
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) ) |
Q (-2,-2), D (-4,1), V (0,3), J (1,-1) |
#4 |
Write a rule to describe the transformation. |
Translation: right 6, down 4 |
#5 |
Desribe how this is a translation |
This guy is on a “slip and slide” He is sliding horizontally. Doesn’t change size or shape. |
