![]() Scalene Trapezium- All the sides and angles of a scalene trapezium are of different measures. Isosceles Trapezium- The legs or non parallel sides of an isosceles trapezium are equal in length. The trapezium is of three different types namely: The legs or non parallel sides of an isosceles trapezium are congruent. It implies that two adjacent angles are supplementary. The sum of two adjacent angles is equal to 180°. The sum of the interior sides of a trapezium is equal to 360 degrees i.e., ∠A + ∠B +∠C +∠D = 360° The sides of a trapezium that are not parallel are not equal except in isosceles trapezium The diagonals of the trapezium intersect each other One pair of opposite sides are parallel in trapezium Here are the different properties of a trapezium: The h is the distance between the two parallel sides which represent the height of the trapezium. In the above figure, we can see sides AB and CD are parallel to each other whereas sides BC and AD are non-parallel. Sometimes, the parallelogram is also considered as a trapezoid with two of its sides parallel. The trapezium is also known as a trapezoid. The parallel sides of a trapezium are called bases whereas non-parallel sides of a trapezium are called legs. The trapezium is a type of quadrilateral with two of its sides parallel. ![]() The three different types of a parallelogram are: If any of the angles of a parallelogram is a right angle, then its other angles will also be a right angle. The diagonal of a parallelogram always bisect each otherĮach diagonal of a parallelogram bisect it into two congruent triangles The consecutive angles of a parallelogram are supplementary ![]() ![]() The opposite angles of a parallelogram are congruent The opposite sides of a parallelogram are congruent Here are the different properties of parallelogram: The area of a parallelogram relies on its base and height. The opposite sides and angles of a parallelogram are equal. A parallelogram is a quadrilateral with two of its sides parallel. ![]()
