What is trapezium and polygon?
The trapezium is a four-sided polygon and a two-dimensional figure which has exactly one pair of parallel sides opposite to each other. A trapezoid is also a four-sided polygon and with one pair of parallel sides opposite to each other.
What is the difference between trapezium and polygon?
A trapezoid is a four-sided shape with at least one set of parallel sides. The area of a trapezoid is the average of the bases times the height. Finally, a polygon is a closed, two-dimensional shape with many sides. Everything from a triangle to an octagon to a megagon is a type of polygon.
What is an area of a polygon?
The area of a polygon is defined as the area that is enclosed by the boundary of the polygon. In other words, we say that the region that is occupied by any polygon gives its area.
What is the formula for finding area of trapezium?
The area of a trapezium can be calculated using the formula: A = ½ × (a + b) × h.
Is trapezoid and trapezium same?
In the US (for some) a trapezium is a four sided polygon with no parallel sides; in the UK a trapezium is a four sided polygon with exactly one pair of parallel sides; whereas in Canada a trapezoid has an inclusive definition in that it’s a four sided-polygon with at least one pair of parallel sides – hence …
Is a trapezium a regular polygon?
If you have looked at the page entitled “Regular Polygons”, you may recall that a polygon is a closed, two dimensional figure with multiple (i.e. three or more) straight sides. It is irregular because adjacent sides are not equal, and adjacent angles are not equal. Shape (d) is a trapezium and a quadrilateral.
Is a rhombus a shape?
A rhombus is a two-dimensional plane figure with a closed shape. It is considered a special parallelogram, and because of its unique properties, it gets an individual identity as a quadrilateral. Rhombus is also called an equilateral quadrilateral, since equilateral means that all of its sides are equal in length.
What is the formula of polygon?
The formula for calculating the sum of interior angles is ( n − 2 ) × 180 ∘ where is the number of sides. All the interior angles in a regular polygon are equal. The formula for calculating the size of an interior angle is: interior angle of a polygon = sum of interior angles ÷ number of sides.
Is a trapezium a parallelogram?
A trapezium is not a parallelogram because a parallelogram has 2 pairs of parallel sides. But a trapezium only has 1 pair of parallel sides.
How to find the area of a trapezium?
A field is in the shape of a quadrilateral ABCD in which side AB = 18m, side AD = 24m, side BC = 40m, DC = 50m and angle A = 90°. Find the area of the field. Question 10. The lengths of the sides of a triangle are in the ratio 4 : 5 : 3 and its perimeter is 96 cm .
What makes a trapezium a four sided polygon?
A trapezium is a four-sided polygon with one pair of parallel sides and one pair of non-parallel sides. Trapezium is having four vertices and four angles. Parallel sides of the trapezium are bases and non –parallel sides known as legs. A Trapezium is also known as a trapezoid.
