**Definition**

Trapezium is a quadrilateral with one pair of sides parallel. We can calculate the area of trapezium by the equation, ½×(a + b)×h, where a, b = sides, h = height.Watch Construction of Trapezium Video to learn more.

A quadrilateral is a simple closed figure bounded by four sides. A trapezium is a type of a quadrilateral in which a pair of opposite sides is parallel.

**Construction of a trapezium of which all the four sides are given and the parallel sides are marked.**

Construct a trapezium in which AB = 6 cm, BC = CD = 4 cm and DA = 5 cm. Also, AB || CD.

Step 1: Draw line segment AB = 6 cm.

Step 2: Mark a point E on AB such that AE = DC = 4 cm.

Step 3: Draw an arc with E as the centre and radius 5 cm.

Step 4: Draw another arc with B as the centre and radius 4 cm, cutting the previous arc at C.

Step 5: Draw an arc with C as the centre and radius 4 cm.

Step 6: Draw another arc with A as the centre and radius 5 cm, cutting the previous arc at D.

Step 7: Join points B and C, points C and D and points D and A.

ABCD is the required trapezium.
