This is a packet that you can use to guide your students notes about the proportionality theorems.
I have drawn a diagram for each of the three proportionality theorems:
-- Angle Bisector
-- Side Splitter
-- Parallel Lines Proportional Theorem
and then I left space for you to guide your students as they fill in a proof of each of these theorems.
I have also provided an example of each theorem.
A handwritten answer key is provided with a proof I do with my students for each of the theorems.
