Answer:
Quadrilaterals 1, 2 and 4 does not represents a parallelogram.
Step-by-step explanation:
We know that, a parallelogram is a simple quadrilateral that have two opposite sides congruent.
Now, according to the options:
1. A parallelogram does not have congruent diagonals without having right angles.
2. A parallelogram does not have consecutive sides equal without being a rhombus.
3. A rectangle is a parallelogram which have both the diagonals of equal length. So, this quadrilateral might represents a rectangle, which is a parallelogram.
4. No two opposite angles of a parallelogram are right angles without the quadrilateral being a rectangle.
5. A rhombus is a parallelogram which have both the diagonals bisecting each other perpendicularly. So, this quadrilateral might represents a rhombus, which is a parallelogram.
Hence, we see that options 1, 2 and 4 does not represents a parallelogram.
