Using Matrices to Perform Geometric Transformations Kendalyn Paulin

How do Matrices apply to Transformations? Remember we can translate a figure up, down, left and right. When we do that we are changing the x and y coordinates of the original figure

Translating a Figure Say we have a triangle with coordinates: A(0,0), B(2,5) and C(7,-1) shown below. The Matrix form would look like this:

Translate Say you want to translate the figure 4 units to the left and 3 units up. You can do this by adding the translation matrix to the original matrix. The result is the final coordinates of the new figure.

Translation Matrices Add these matrices to translate figure…. Up y units Down y units Right x units Left x units
