Another bonus about this is that in both cases we can also prove that the side AD does 3 things, bisects

On the second equation, we can also use the AAA axiom: Given: m

Be careful that the AAA axiom could prove only that the shapes are similar as the angles measure don’t relate to the lengths of sides

Exactly that's why I always think of it that you need to know that there's at least 1 side that's congruent, to know for certain they're congruent triangles, which is why ASA is the same as AAS, it's basically 3 angles and a side since if 2 angles are congruent the third will definitely be congruent as well

iSoSceleS when he mentioned he forgets how to spell that word, i remembered i forget about the SSS law if you look at the word iSoSceleS like this, you remember it has 3 S's and that reminds me of the SSS law!

What do I do if only one side of the triangle has an indicator (aka the little line on the side that determines if a side is congruent) Wasn't sure what it was called

You just look at it and try and see if they look the same length
