 Hi, and welcome to the session. Today we will discuss the following question. The question says state whether true or false and the statement is all parallelograms are trapeziums. Let's see the figure of a parallelogram and a trapezium. Alright, here we have a trapezium and a parallelogram. Let's recall the definition of a trapezium. It says in a trapezium one pair of opposite sides is parallel, that is AD is parallel to BC. Now, in a parallelogram we have both the pairs of opposite sides as parallel, that is PQ is parallel to SR and PS is parallel to QR. That means a parallelogram satisfies all the conditions of a trapezium and thus a parallelogram is a special trapezium with both the pairs of opposite sides parallel. Thus our statement all parallelograms are trapeziums is true. So here we finish this session. Hope you must have enjoyed it. Goodbye, take care and have a nice day.
