 Hi and welcome to the session. Today I will help you with the following question. The question says, state whether true or false. For this statement, all squares are trapeziums. Let's see its solution with the help of this figure. A trapezium and a square. Let's see what is a trapezium. A trapezium is a quadrilateral in which one pair of opposite sides is parallel that is ad is parallel to bc. Now in a square we know that the opposite sides are parallel that is pq is parallel to sr and ps is parallel to qr. That means both the pairs of opposite sides are parallel. So we can say that a square is a special trapezium with both the pairs of opposite sides parallel. Thus this statement all squares are trapeziums is true. So with this we finish this session. Hope you must have understood the concept. Goodbye and take care.
