The rap to end all raps. Students look forward to this rap all through middle school. It covers congruence, basic transformations, corresponding sides and angles, CPCTC, proving congruence with SSS, ASA, and SAS. Be prepared to be a fast rapper if you want to perform this for the class. My students LOVE the day I rap for them near the end of 8th grade, especially since this is one I wrote. I have included a link to my music video which is a karaoke version of the song with my lyrics. If you know the Fresh Prince of Bel Air, you can easily rap along.
