![]() The opposite sides of an isosceles are of the same length.Parallel means they follow the same path at different points but can never meet. The bases (the top and bottom line) are parallel to each other.Though trapezoids are quadrilaterals, they have properties that make them stand out from other quadrilaterals. A scalene trapezoid exhibits all properties of a trapezoid since it has two parallel sides and two non-parallel sides, even though they have different lengths. Due to this feature, a scalene trapezoid forms four angles of different measures at the vertices. It has sides that are not congruent and have different lengths. Scalene trapezoidĪ scalene trapezoid is also called a non-isosceles trapezoid. Similar to the properties of other quadrilaterals, the interior angles of an isosceles trapezoid add up to 360 degrees. The diagonals and the base angles of an isosceles trapezoid are equal. Isosceles trapezoidĪn isosceles trapezoid is a trapezoid with its top and bottom as parallel lines, while the remaining pair of lines are non-parallel and have equal length. ![]() Since there is a right angle formed at one of the bases, automatically, another right angle is formed at the other base. It is also called a right-angled trapezoid since it has a right angle of 90 degrees. Trapezoids can be classified into three groups:Ī right trapezoid is a trapezoid with one of its legs perpendicular to both of the bases. To come to an agreement, we can say that the exclusive definition of a trapezoid states that it has no opposite parallel sides, while the inclusive one states that it has at least one pair of opposite parallel sides. According to the second description, a parallelogram qualifies to be a trapezoid, but the first description disqualifies this statement. Some schools say that a trapezoid can have only one or no pair of parallel sides, while others say that it can have more than one pair of parallel sides. There are still disagreements on the definition of a trapezoid. The sum of all the interior angles adds up to 360 degrees. The perpendicular distance between the parallel sides is known as altitude. It has one set of opposite parallel sides known as the base and another set of non-parallel sides known as the legs or laterals of a trapezoid. It is a 2D flat closed shape with four sides. What Is a Trapezoid?Ī trapezoid is a quadrilateral with one pair of parallel sides. Basically, they have the same shape with different structures because a trapezoid is trapezium-like with no opposite parallel sides. Till date, there is still confusion whether trapezoid and trapezium are the same thing. One was the trapezium and had only two pairs of parallel lines, while another one was the trapezoid which had one or no pair of opposite parallel lines. Later, Proclus introduced two types of trapezia. They were square, rectangle, rhombus, and rhomboid with four sets of parallel sides, while the last one was a trapezia which had only two sets of parallel sides. Euclid, an ancient Greek mathematician, was the one who named the five quadrilaterals.
