Question: the diagonals of a parallelogram are represented by r1?
Answer: The diagonals of a parallelogram are represented by vector R1 = 3i + 2j- 7k and vector R2 = 5i +6j -3k. ... In a parallelogram, the longer diagonal corresponds to A + B, and the shorter diagonal corresponds to A - B. Let us find | R¹| and | R²|, where R¹ and R² are the two diagonals of the parallelogram.
