Yes its quite possible to have an isosceles trapezoid which will have 2 equal base angles and 2 equal angles above which all 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
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 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.
Not for all trap. Only for an isosceles trapezoid. Well, for an Isosceles trapezoid, it could be any of the two diagonals! In order to have an isosceles trapezoid with the diagonals equal, the isosceles part MUST be precise and specific.
