I'm struggling with my geometry badly, i have until the beginning of august to get 3 more credits and this class is my bane. me out.

We see 2 congruent angles (A and B) that adjacent to the side AB,

this is Angle- Side-Angle Theorem. (A)

For right triangle it can be called Leg-Angle theorem. (F)

It could be Side- Angle- Side theorem, because AB=XY, BC=YZ, angle B=angle Y, but for right triangle it names Leg-Leg theorem. (B)

ASA = Angle, Side, Angle

LL= Leg, Leg

LA= Leg, Angle

All three of these show congruence between two triangles.

Are you taking the class with apex? If so, we are taking the same class! :D
