- You are asked to compare vectors for:
a) and ,
Solution Explanation:
In a parallelogram, the diagonals bisect each other at their intersection point. This means:
- Point divides each diagonal into two equal segments:
Thus:
- and are equal in magnitude and direction:
- Similarly, and are also equal in magnitude and direction:
This is a fundamental property of parallelograms, as their diagonals always bisect each other.
