我想問下會考比唔比証similar triangle用AA e個reference?
即係有2個三角形(A同B),我只係証明左佢地2隻角一樣,
就話佢地similar ...可唔可以咁?定一定要証晒3隻角?
e.g.
angle a =angle b
angle c =angle d
triangleA ~triangleB(AA)
定一定要
angle a =angle b
angle c =angle d
angle e=180-angle a-angle c
angle f=180-angle b-angle d
angle e=angle f
triangleA ~triangleB(AAA)
