Answer 1

Step-by-step explanation:

every trapezium is a parallelogram is not true

Answer 2

Every trapezium is a parallelogram is not true. (Option c)

• A trapezium is a closed figure that has one pair of parallel sides and another pair of non-parallel sides.
• The parallel pair of sides are unequal in length and are called the bases.
• The opposite sides of a parallelogram are parallel and so trapezium is not a parallelogram.
• A square has all the properties of a rhombus and rectangle and each of these closed figures are a quadrilateral.
