The line segmentthat connects the midpoints of the legs of a trapezoid is called the mid-segment. So to summarise the properties of a trapezium: a) A quadrilateral with a pair of parallel sides. Take me to revised course. One pair of non-parallel sides. Properties Of Trapezium. A trapezium doesn’t have rotational symmetry so the order of rotational symmetry is 1. How do you get paint to stick to shiny surfaces? You can work out the area of a trapezium by using the formula A = ½(a+b)h. Where a and b are the lengths of the parallel sides and h is the shortest distance between the two parallel sides. In a trapezium if the parallel sides are equal the it is called as an isosceles trapezium . Angle: The sum of anglesin a trapezoid-like other quadrilateral is 360°.

Summarizing what we have learnt so far for easy reference and remembrance: The main property of a trapezium (as known in Great Britain) or trapezoid (as known in the United States) is that it is a 4 side shape with exactly one pair of parallel sides. b) 0 or 1 lines of reflectional symmetry. Opposite angles are congruent. The pair of parallel sides is called the base while the non-parallel sides are called the legs of the trapezoid. 1.In a trapezium if the parallel sides become equal then it is called as a parallelogram. An isosceles trapezium is a trapezium in which the non-parallel sides are equal in measure. Previous Topic Previous slide Next slide Next Topic. Opposite angels are congruent (D = B). In an isosceles trapezium one pair of opposite sides are equal but not parallel. None of the sides, angles, and diagonals are congruent. No sides, angles and diagonals are congruent. So a = 8 and b = 10. All you need to do now is substitute these 3 values into the formula: Alternatively, since the trapezium was symmetrical you could split up the trapezium into 2 triangle and a rectangle: Area of each triangle = (6 × 1) ÷ 2 = 3cm², So the total area of the trapezium is 48 + 3 + 3 = 54 cm². Answer: A trapezium can be drawn in different ways, so the properties can vary, but it must have exactly one pair of parallel sides. Diagonals of a trapezium bisect each other on intersection. A parallelogram may also be called a trapezoid as it has two parallel sides. Move points B, C, D or E to change the size and shape of the Trapezium. Answer: It will have 0 lines of reflectional symmetry. Properties of a square. It is a Four-sided Closed Figure with a sum of interior angles 360°. Depending on how the trapezium is drawn determines how many lines of symmetry if has. A trapeziumhas the following properties: A Trapeziumhas two parallel sides and two non-parallel sides. Diagonals bisect each other and each diagonal divides the, The properties of trapezoid apply by definition (parallel bases). Do diagonals of trapezium bisect each other? The legs are congruent by definition. Important Formulas for a Trapezium. Learn more. What are the 6 properties of a parallelogram? The diagonals of trapezium bisect each other.
