It is customary, with congruent triangles, to "letter" the triangles' names in a corresponding order: vertex A will correspond to vertex D, vertex B to vertex E, and vertex C to vertex F, so triangle ABC is . My advice (currently) is to assume $\angle ABC$ or $A\widehat{B}C$ is oblique (acute or obtuse) and specify reflex $A\widehat{B}C$ or reflex $\angle ABC$ if you need to. I think reflex $\angle ABC$ is a little contradictory but if you imagine an of then it makes perfect sensereflex of $\angle ABC$. Why is that so many apps today require a MacBook with an M1 chip? 1.
