Question

hello guys plz answer the question

Answer 1

I guess the answer is none.
For the quadrilateral to be square or rectangle, the angle between two adjacent line must be 90°
Slope of first line = -l/m
Second line = -l/m
Third and fourth line = -m/l
None of which when joined makes 90 °.
If you want to check, you multiply them, if the product is -1, then the lines are perpendicular, but none of the given line are.
For a trapezium two opposite line should be parallel and the other two opposite line should not be parallel, but here the set of adjacent line are parallel.
So, the answer is a parallelogram.
Hope it may help you !!!!!
