Isosceles Trapezium vs. Trapezium: Know the Difference
By Shumaila Saeed || Published on February 25, 2024
An isosceles trapezium is a trapezium with two opposite sides parallel and the non-parallel sides being equal in length. A trapezium, in general, is a quadrilateral with only one pair of parallel sides.
Key Differences
An isosceles trapezium is a quadrilateral with one pair of parallel sides and non-parallel sides being equal in length, creating congruent base angles. In contrast, a trapezium is simply a quadrilateral with only one pair of parallel sides, without any restrictions on the other sides.

The isosceles trapezium is symmetric along the perpendicular bisector of its bases, giving it a mirror-image quality. On the other hand, a trapezium does not necessarily have this symmetry and can have sides and angles of varying lengths and degrees.

In an isosceles trapezium, the diagonals are equal in length. However, in a general trapezium, the diagonals are not required to be of equal length.

The angles opposite each other in an isosceles trapezium are equal. In a standard trapezium, there is no such requirement for the opposite angles to be equal.

The term "isosceles trapezium" is more specific and denotes a particular type of trapezium, while "trapezium" is a broader term encompassing various forms of quadrilaterals with only one pair of parallel sides.
