Because it does't have 4 equal sides and 4 equal angles as for example such as a square.
A trapezoid unless it is an isosceles trapezoid otherwise it can be known as an irregular quadrilateral
No, not every trapezoid is an isosceles trapezoid.
irregular polygons are just polygons that do not have equal angles and side so a scaling and isosceles triangles are 2 and trapezoid is another.
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
No, a cut cannot be made between two parallel sides of an isosceles trapezoid to create two isosceles trapezoids. An isosceles trapezoid has only one pair of parallel sides, so cutting between them would result in two separate shapes, neither of which would be an isosceles trapezoid. The resulting shapes would likely be irregular quadrilaterals or triangles, depending on the location of the cut.
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.
