1.2.1 Introduction to Transformations 431

By the end of this playlist I can...
...define and recognize translations, reflections and rotations
...perform a given translation, reflection or rotation in the coordinate plane
...determine the transformation that maps a pre-image to an image
...use algebraic rules to describe transformations in the coordinate plane (x, y) → (      ,      )

Given the point A(2, 5), what are the coordinates of A', the image of point A after a reflection over the x-axis?
Coordinates should be entered using parentheses and no spaces, i.e. (-5,7)

Given the point B(7, -5), what are the coordinates of B', the image of point B after a reflection over the y-axis?

10

Given the point C(3, -5), what are the coordinates of C', the image of point C after a translation left 6 and up 3?

10

Given the point D(3, -5), what are the coordinates of D', the image of point D after a 90 degree counterclockwise rotation about the origin?

10

Given the point E(-7, -3), what are the coordinates of E', the image of point E after a 180 degree counterclockwise rotation about the origin?
