Reflektimi i pikes

Le te jete nje pike a=(ax, ay) ne rrjetin koordinativ x-y. Ne nje bashkesi me 3 pika a, b dhe r pika r=(rx, ry) quhet reflektimi i pikes a nese eshte rrotullimi 180 grade i pikes a rreth pikes b.

Pyetja: Shkruaj nje program i cili do te lexoje nga perdoruesi koordinatat e pikes a: ax, ay dhe koordinatat e pikes b: bx, by dhe te shfaqi ne ekran koordinatat e pikes r: rx, ry

Specifikimi i inputit
Cdo koordinate e dhene do te jete midis kufijve 0 ≤ x ≤ 2000 0 ≤ y ≤ 2000. Do te jepen 4 koordinata sipas rendit ax ay bx by te ndare ne rrjeshta te ndryshem.

Specifikimi i outputit:
Shfaq vlerat e koordinatave rx ry te ndare nga nje hapesire.

Hint:
Ushtrimi eshte me i thjeshte sec duket. Mjafton ta zgjidhni matematikisht
problemin dhe cdo gje behet e qarte.
