Working out the area of a trapezium is a common question on most exam papers, and you can use trapeziums to estimate the area enclosed between a curve and the coordinate axes (this is known as the trapezium rule). The angles on either side of the bases are the same size/measure (congruent). Answer: It will have 0 lines of reflectional symmetry. The bases (top and bottom) of an isosceles trapezoid are parallel. If the non-parallel sides of a trapezium are of equal length, we call it an isosceles trapezium. Diagonals intersect each other. 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.

Properties of Trapezium Every trapezium has the following properties: One pair of opposite sides are parallel. The sum of the internal angles of the trapezium is 360° i.e., ∠A + ∠B + ∠C + ∠D = 360°. The legs are congruent by definition. Trapezium -Definition, Properties, Types and Area Trapezium Definition :- A trapezium is a type of quadrilateral (2D shape) in which two opposite sides are parallel and two opposite sides are not parallel.Parallel sides are referred as the bases and non-parallel sides are … The diagonals (not show here) are congruent.
