2. Isosceles trapezoid - Wikipedia

   en.wikipedia.org/wiki/Isosceles_trapezoid

   Any non-self-crossing quadrilateral with exactly one axis of symmetry must be either an isosceles trapezoid or a kite. [5] However, if crossings are allowed, the set of symmetric quadrilaterals must be expanded to include also the crossed isosceles trapezoids, crossed quadrilaterals in which the crossed sides are of equal length and the other sides are parallel, and the antiparallelograms ...

3. Trapezoid - Wikipedia

   en.wikipedia.org/wiki/Trapezoid

   The other two sides are called the legs (or the lateral sides) if they are not parallel; otherwise, the trapezoid is a parallelogram, and there are two pairs of bases. A scalene trapezoid is a trapezoid with no sides of equal measure, [3] in contrast with the special cases below.

4. Cyclic quadrilateral - Wikipedia

   en.wikipedia.org/wiki/Cyclic_quadrilateral

   Any square, rectangle, isosceles trapezoid, or antiparallelogram is cyclic. A kite is cyclic if and only if it has two right angles – a right kite.A bicentric quadrilateral is a cyclic quadrilateral that is also tangential and an ex-bicentric quadrilateral is a cyclic quadrilateral that is also ex-tangential.

5. Talk:Isosceles trapezoid - Wikipedia

   en.wikipedia.org/wiki/Talk:Isosceles_trapezoid

   Definition: A parallelogram is a quadrilateral that has both pair of opposite sides parallel. Definition: An isosceles trapezoid is a trapezoid, whose legs have the same length. It is clear from this definition that parallelograms are not isosceles trapezoids. Ok, now that definitions have been laid out, we can prove theorems. Here are some ...

9. Antiparallelogram - Wikipedia

   en.wikipedia.org/wiki/Antiparallelogram

   [6] [7] The convex hull of an antiparallelogram is an isosceles trapezoid, and every antiparallelogram may be formed from an isosceles trapezoid (or its special cases, the rectangles and squares) by replacing two parallel sides by the two diagonals of the trapezoid. [4]
