Answer:
KITE, TRAPEZIUM and A Concave quadrilateral
Step-by-step explanation:
PARALLELOGRAM: A quadrilateral in which opposites sides are PARALLEL and EQUAL.
So, Any quadrilateral which does NOT have its opposite sides being parallel or equal is not a parallelogram.
So, such quadrilaterals are:
1. KITE : A kite is not a parallelogram as it has no parallel lines at all.
2. TRAPEZIUM : A trapezium has ONLY ONE pair of opposite sides parallel.
3. A Concave quadrilateral does not have parallel sides.
