प्रश्न
If `vec"a"` and `vec"b"` are adjacent sides of a rhombus, then `vec"a" * vec"b"` = 0
पर्याय
True
False
उत्तर
This statement is False.
Explanation:
If `vec"a" * vec"b"` = 0 then `vec"a" * vec"b" = |vec"a"||vec"b"| cos 90^circ`
So the angle between the adjacent sides of the rhombus should be 90° which is not possible.
