In this "Math Made Easy" geometry episode, you learn how to prove that two triangles are congruent (equal) by using the "side-side-side" evidence. By using "side-side-side" to prove that two triangles are congruent, you are stating that all the respective corresponding sides of two triangles are equal in length thus proving the triangles are congruent. The narrator in this tutorial provides you with definitions about statements, proofs, and congruency. This becomes useful when setting up a table with two sides; one side being the statement for congruency and the other side listing the proofs. In this episode, the proof being demonstrated is "side-side-side". The video shows you how to denote the corresponding congruent sides on the table you created. After, the video you will understand how to set up a table to prove that two triangles are congruent.
