You will be able to prove these triangle congruent using SAS, SSS, HL, and AAS

anonymous · Answer

Wait, you can't use AAS as there is not another angle

anonymous · Answer

Anyway, all you have to do is match up the parts in the order they are listed. If you see SSS, check to see if three sides are congruent. If you see SAS, look to see if there are two congruent sides flanking a congruent angle. HA and LA are not real congruence theorems.

So SAS,SSS,HL ??? @graham69

yes @yoda5657

@graham69 I have some questions I need you to check http://prntscr.com/3tj41s ^^^

Okay, I just looked up HA and LL, they do exist, I just never learned about them. Sorry. Anyway, these triangles are congruent by HL, AAS, and HA. HA and LL apply only to right triangles, and occur when the hypotenuse and an acute angle are congruent on both triangles, and LL occurs when two legs (other than the hypotenuse) are congruent on both triangles. Sorry for that.
