No, not every trapezoid is an isosceles trapezoid.
An isosceles trapezoid
area congruent angles congruent segment
If the two sides which are not parallel have equal lengths, then the trapezoid is called an isosceles trapezoid (standard trapezoid has unequal sides). The base angles in an isosceles trapezoid are equal in measurement, also I know that a trapezoid with two nonparallel sides the same length is called an isosceles trapezoid.
The base angles are congruent in an isosceles trapezoid
The general formula to calculate area of a trapezoid ( and an isosceles trapezoid) is:AREA=(Sum of parallel sides)(Distance between parallel sides)/2. And if you find this formula difficult, calculate separately the area of two right angled triangles and a rectangles. For more details, contact at saqibahmad81@yahoo.com

An isosceles trapezoid
Yes, an isosceles trapezoid is symmetrical.
how is an isoscelels trapezoid related to a isosceles triangle
In an isosceles triangle and an isosceles trapezoid, both base angles are congruent
area congruent angles congruent segment
The diagonals of an isosceles trapezoid are equal in lengths
If the two sides which are not parallel have equal lengths, then the trapezoid is called an isosceles trapezoid (standard trapezoid has unequal sides). The base angles in an isosceles trapezoid are equal in measurement, also I know that a trapezoid with two nonparallel sides the same length is called an isosceles trapezoid.
There is no simple formula and, in any case, the answer will depend on what information about the trapezoid is given.
If you extend the two legs of an isosceles trapezoid until they intersect, you get an isosceles triangle.
