Thanks for the query.
A trapezoid is also known as a trapezium. It has four sides with at least one pair of parallel sides though the definition varies at different places.

A solid trapezoid has 12 sides
In trapezoid ABCD, the sides AB and CD are parallel and AB > CD. Point P is in the interior, dividing the trapezoid into 4 triangles with areas CPD = 2, CPB = 3, BPA = 4, APD = 5. What is AB/CD equal to?
Trapezoid as shown has two parallel sides with length 5 and 15 & two diagonals with length 12 and 16. What is its area?
Suppose ABCD is an isosceles trapezoid with bases AB and CD and sides AD and BC such that |CD| > |AB|. Also suppose that |CD| = |AC| and that the altitude of the trapezoid is equal to |AB|
If |AB|/|CD| = a/b where a and b are positive coprime integers, then find a^b?
