It would depend on the triangles, but assuming they were equilateral or isosceles, a trapezoid if alternated in a line.
The Great Pyramids at Giza are, but the Meso-Americans were truncated.
Absolutely. Any two congruent right triangles will form a rectangle, and if the right triangles are isosceles right triangles, they will form a square.

Inscribed triangles in a rectangle are identical right triangles but they are rotated 180 relative to each other.

An isosceles triangle can be divided into 4 smaller, identical isosceles triangles. Each of these can then be divided into 4, and each of them ... So, the answer to the question is infinitely many.

In general, a parallelogram. But if the triangles are joined along their odd side, a rhombus.
There are normally no parallelograms within an isosceles triangle unless you put them there yourself.

20 isosceles triangles with each base being a side of the 20-gon, and the opposite vertices at the center of the polygon.
If you have 2 EQUILATERAL triangles, and you stack them on their respective hypotenuses, the result: SQUARE. If you have 2 ISOSCELES triangles, and you stack them on their respective hypotenuses, the result: RECTANGLE. If you have 2 OBTUSE triangles, and you stack them on their respective hypotenuses, the result: PARALLELOGRAM.
Well, honey, you're gonna need 20 short isosceles triangles to build that fabulous Icosahedron. Each face of the Icosahedron is made up of an isosceles triangle, and there are 20 faces in total. So, do the math and get building, darling!
It can be, if all the vertices of the pentagon are joined to its centre. But if they are joined to any other point, it will not be.
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.
