A four-sided polygon with no parallel sides and no sides equal; a simple convex irregular quadrilateral. ; The sum of the exterior angles of a convex polygon, taken one at each vertex, is 360 o. There are many types of quadrilateral, each with different properties. The parallel sides of a trapezium are in a ratio 2 : 3 and their shortest distance is 12 cm. Area of Quadrilateral: Trapezium. A trapezium is a type of quadrilateral. As a adjective quadrilateral is having four sides. In the United States, a 'trapezium' is defined as a quadrilateral which has no parallel sides. Parallelogram ,Trapezium , Rectangle , Rhombus , Square etc are some examples of quadrilaterals. In Euclidean geometry, an isosceles trapezoid (isosceles trapezium in British English) is a convex quadrilateral with a line of symmetry bisecting one pair of opposite sides. No. Properties of Trapezium. A trapezium is a quadrilateral which has one pair of opposite sides parallel. • Non-parallel sides are called legs or lateral sides. Square, rectangle, rhombus, parallelogram, kite and trapezium are all quadrilaterals. A trapezium has one pair of opposite sides parallel. These example sentences are selected automatically from various online news sources … A square‘s sides are tripled producing an area of 81 square feet. A trapezium has one pair of opposite sides that are parallel lines. You can easily see that a rectangle may have four 90° interior angles, but it need not have four equal-length sides. A Trapezium is a quadrilateral which has two parallel sides in either of the directions.
