When we have two triangles, how can we tell if they're congruent they may look the same, but you can be certain by using one of several triangle. Sal introduces and justifies the sss, sas, asa and aas postulates for congruent triangles theorems concerning triangle properties show all questions. Sal reviews all the different ways we can determine that two triangles are similar this is similar to the congruence criteria, only for similarity.
