Translations
What are the three transformations we have learned about?
What are translations, reflections, and rotations?
Find the new coordinates of (10,12) if you translate the point three units left and 4 units up.
What is (7,16)?
Find the new coordinates of (3,-2) after you reflect the point over the x-axis.
What is (3,2)?
Which of the following is not a rigid motion transformation?
What is a dilation?
Write the rule of point (x,y) after it moves 3 spots to the left and 7 spots up.
What is (x, y)->(x-3,y+7)?
What is the coordinate of the point (0, 5) when it is reflected over the y-axis?
What is (0, 5)?
The quadrants of the coordinate plane are numbered in this direction.
Hint: clockwise or counterclockwise
What is counterclockwise?
The definition of this term means "the figure stays the same size and same shape"
What is a rigid motion?
Describe the translation for this notation: (x,y) --> (x + 8, y + 4)
What is a translation of 8 units to the right and 4 units up?

What is (1,6)?
This rule demonstrates which type of transformation:
(x, y)->(x-6, y+2)
