Translations
A translation is when you do this to a figure.
What is move it right, left, up, or down?
A reflection is when you do this to a figure.
What is flip it or make a mirror image of it?
A rotation is when you do this to a figure.
What is spin it?
A dilation is when you do this to a figure.
What is make it bigger or smaller?
A transformation in which a shape is moved right, left, up and down.
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)?
Find the new coordinates of (5,4) after you rotate the point with 180º.
