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

Draw a trapezium and state the pair of parallel side

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 segment joining the middle points of two non-parallel sides of a trapezium is parallel to the parallel sides and half of their sum.

The parallel sides of a trapezium are 25cm and 13cm; its nonparallel sides are equal,each being 10cm, find the area of the trapezium.
