Scalene Trapezoid
A scalene trapezoid is a type of trapezoid where none of the sides are congruent. It has one pair of parallel sides, while the other two sides are non-parallel.
The two parallel sides are known as the long base and the short base, corresponding to the longer and shorter of the parallel sides.
The two non-parallel sides are referred to as the oblique sides.
The perpendicular distance between the two bases is called the height (h) of the trapezoid.
In a scalene trapezoid, all four sides are of different lengths.
The angles in a scalene trapezoid don’t follow any specific pattern of equality or complementarity as seen in other trapezoids.
Note: Unlike other trapezoids, such as the right or isosceles trapezoid, the scalene trapezoid lacks any particular symmetry properties.
The area (A) and perimeter (P) of a scalene trapezoid can be calculated using the standard formulas for a trapezoid.
$$ A = \frac{(b_1+b_2) \cdot h}{2} $$
$$ P = b_1+b_2+l_1+l_2 $$
Here, b1 and b2 are the lengths of the bases, l1 and l2 are the lengths of the non-parallel oblique sides, and h is the height, or the perpendicular distance between the bases.
And so on.
