No, not every trapezoid is an isosceles trapezoid.
An isosceles trapezoid
No, but they are both 4 sided quadrilaterals.
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
They are both 4 sided quadrilaterals but a trapezoid has different properties than an isosceles trapezoid which has 2 equal base angles.
Properties of quadrilaterals
No, not every trapezoid is 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
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.
If you extend the two legs of an isosceles trapezoid until they intersect, you get an isosceles triangle.
No. It can be but need not be.
