கொடுக்கப்பட்டுள்ளவை,

ஒரு கோட்டின் இரு புள்ளிகள் (-2, -1) மற்றும் (-5, -3) ஆகும்.

கோட்பாடு:/சூத்திரம்:

(x1, y1) மற்றும் (x1, x2) ஆகிய புள்ளிகளை இணைக்கும் கோட்டுத்துண்டின் நடுப்புள்ளி = [(x1 + x2)/2, (y1 + y2)/2]

கணக்கீடு:

(-2, -1) மற்றும் (-5, -3) ஆகிய புள்ளிகளை இணைக்கும் கோட்டுத்துண்டின் நடுப்புள்ளி

⇒ [(-2 – 5)/2, (-1 – 3)/2] = (-7/2, -2)
