(-2,3), (6,7), (8,3) എന്നിവ ഒരു സാമാന്തരികത്തിന്ടെ ശീർഷങ്ങളാണെങ്കിൽ നാലാമത്തെ ശീർഷം ഏത് ?

A(1,0)

B(0,1)

C(-1,0)

D(0,-1)

Answer:

D. (0,-1)

Read Explanation:

Given three vertices of a parallelogram:

A(-2, 3),B(6, 7),C(8, 3)

In a parallelogram, diagonals bisect each other, so the fourth vertex (D) can be found using:

D = A + C - B
Add A and C

(-2 + 8, 3 + 3) = (6,6)

Subtract B

(6 - 6, 6 - 7) = (0,-1)

Final Answer: (0, -1)
