An isosceles trapezoid is a quadrilateral that has parallel bases of different lengths, two equal sides and the lateral base angles are equal.
Interior angles add up to 360 degrees
Exterior angles add up to 360 degrees

No, not every trapezoid is an isosceles trapezoid.
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.
A quadrilateral that has one (and only one) pair of parallel sides is a trapezoid. It is isosceles of the non-parallel sides are of equal length. It is right angled if any one of the angles is 90 degrees.
what is isosceles
No. It can be but need not be.
