Voici l’algorithme qui est tombé au Bac S spécialité maths au Liban en mai 2013 :

Faire fonctionner cet algorithme pour n = 5 en complétant le tableau ci-dessous :

a b c i n affichage

a ← 3

b ← 8

Pour i variant de 2 à n faire

c ← a

a ← b

b ← 5a – 6c

Fin Pour

Afficher b
Pourriez m'aider s'il vous plaît. C'est du programme de Python.

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
