Explain how this figure is a trapezium. Which of its two sides are parallel? (Fig 3.32)

explain how DEAR is a trapezium. Which of its two sides are parallel?

Draw a trapezium. Write names of its parallel sides.

How many pairs of sides are parallel in a Trapezium?

In the given figure , ABCD is a trapezium in which the parallel sides AB,CD are both perpendicular to BC. Find the area of the trapezium :

The area of a trapezium is half the product of its height and sum of parallel sides.

A circle is inscribed in a trapezium in which one of the non-parallel sides is perpendicular to the two parallel sides. Then A) the diameter of the inscribed circle is the geometric mean of the lengths of the parallel sides B) the diameter of the inscribed circle is the harmonic mean of the lengths of the parallel sides C) the area of the trapezium is the area of the rectangle having lengths of its sides as the lengths of the parallel sides of the trapezium D) the area of the trapezium is half the area of the rectangle having lengths of its sides as the lengths of the parallel sides of the trapezium

Prove that the line segment joining the mid-point of two transverse sides of a trapezium is parallel to its parallel sides.

Prove that the line segment joining the mid-points of the lateral sides of any trapezium is parallel to any of its parallel sides.
