Operations that alter the form of a figure. Examples: translations, reflections, dilations, and rotations.
What is transformations?
The transformation that flips a shape
What is reflection?
Find the coordinates of X', Y', and Z' when triangle XYZ with X(0,3), Y(3, -2), and Z(4,0) is translated by <-5, 1>.
What is X'(-5, 4), Y'(-2, -1), and Z'(-1, 1)?
The coordinates of M', N', and O' when triangle MNO with M(-2, -4), N(-3, 1), and O(0, 2) is reflected over the line y=0.
What is M'(-2, 4), N'(-3, -1), and O'(0, -2)?
In Dilations, segments lengths are not preserved, but these features are. (name at least 2)
What are angle measures, betweenness of points, and collinearity?
The line of reflection when A(-2, 0), B(1, 3), and C(3, -4) is reflected to A'(2, 0), B'(-1, 3), and C'(-3, -4).
What is the y-axis (or x=0)?
A transformations that preserves distance.
What is a translation/reflection/rotation?
The rule for reflecting across the line y=-x.
What is (x,y)-->(-y,-x)?
