No, not every trapezoid is an isosceles trapezoid.
An isosceles trapezoid
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
An isosceles triangle and a isosceles trapezoid.
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 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.
what is isosceles
Yes, an isosceles trapezoid does have rotational symmetry. An isosceles trapezoid is a quadrilateral with two parallel sides of equal length, which means it can be rotated around its center by certain angles (180 degrees, in this case) and still look the same. This is an example of rotational symmetry, where the shape can be rotated and still appear unchanged.
