A trapezoid is a quadrilateral shape that has four sides of unequal lengths two of which are parallel to each other.
An isosceles trapezoid also has two parallel sides but with two other sides being of equal length.

Another trapezoid that has the same dimensions and angles will be congruent to it.

No, the diagonals of a trapezoid are not always congruent. A trapezoid is a quadrilateral with at least one pair of parallel sides. The diagonals of a trapezoid connect the non-parallel vertices, and their lengths can vary depending on the specific dimensions of the trapezoid. In a trapezoid where the non-parallel sides are of equal length, the diagonals will be congruent, but this is not always the case.
Area of a trapezoid measured in square units = 0.5*(sum of parallel sides)*height
