Correct way to prove similar and congruent triangles? (1 Viewer)

[spiderlemonade]

Uh so basically i found out theres more than one way to prove similarity/congruency and now idk which one to use
My proofs for congruence are AAS, SAS, and SSS. My tutor said to not use RHS, but my school does :/
My proofs for similarity are SAS, SSS and AA(equiangular). but again, my school doesn't use AA, instead AAS

anyways my main problem is that i was talking with a friend, and at his school they explicitly say to not use any of the things i said above or they get marks deducted. instead they have to write full written statements like instead of SSS it's "three pairs of matching sides are in the same ratio" and instead of AA it's "two angles of one triangle are equal to two angles of the other triangle" asdfghjkl;

A full sentence for proving similarity and congruence sounds diabolical

ohhh I know what you mean. It really depends on your school and the way your teachers mark exams, whether writing 'SAS' is good enough or 'Side Angle Side' is needed to be written fully to get the marks. Just do whatever your teacher/school says to do. If the abbreviation is ok with them then ig don't write the full thing

its really common though for schools to ask students to write the full thing bc i heard in hsc some abbreviations aren't allowed/recognized

wot
what even is AAS for similarity surely thats only for congruency?

Congruency and similarity proofs aren't used in mx2 mx1 or advanced don't bother learning it at all

i dont think its in standard,

its good to know and understand but youre not gonna use it again, you wont even use it in yr 10 lmao

I think I learnt in once in year 9 but never again

real i dont even remember how to do it

yeah thats what my tutor said in year 7 but my school teacher says otherwise so idk who to believe

Bruh ik i just dont wanna lose marks in year 9 for something dumb like this
