The points A (-2, -1), B (1, 0), C (4, 3) and D (1, 2) are corners of a
Correct Answer: Description for Correct answer:
\( \Large AB = \sqrt{3^{2}+1^{2}}=\sqrt{10} \)
\( \Large BC = \sqrt{3^{2}+3^{2}}=3\sqrt{2} \)
\( \Large CD = \sqrt{3^{2}+1^{2}}=\sqrt{10} \)
\( \Large DA = \sqrt{3^{2}+3^{2}}=3\sqrt{2} \)
Therefore, Diagonal AC = \( \Large \sqrt{6^{2}+4^{2}}=\sqrt{52} \)
and diagonal BD = \( \Large \sqrt{0+2^{2}}=2 \)
Since opposite sides are equal and the diagonals are not equal, hence ABCD is a parallelogram.
