A = (2, 4) এবং D = (-1, 3)
অনুসৃত সূত্র :
A = (a, b) এবং B = (c, d) এবং D হলে AB রেখার মধ্যবিন্দু
D = (x, y)
⇒ x = (a + c)/2 এবং y = (b + d)/2
গণনা:
ধরা যাক, B-এর স্থানাঙ্ক হবে (x, y)
প্রশ্ন অনুযায়ী,
(2 + x)/2 = - 1
⇒ 2 + x = - 2
⇒ x = - 4
এছাড়াও,
(4 + y)/2 = 3
⇒ 4 + y = 6
⇒ y = 2
∴ B এর স্থানাঙ্ক = (-4, 2)
