It depens. It could be 2, it could be 4. It depends on the triangle size.

right triangles and
They are alike inasmuch that a rectangle can be split into two right angle triangles
A=l*w A=8*4 A=32 diagonal cuts the rectangle into two congruent triangles. 32/2 = 16
No it can not you can try all these different ways but it will not work
Two of them
there are 4 triangles and 1 rectangle in an rectangular pyramid

Two right angle triangles, normally scalene triangles. However, if the rectangle is for example a square, then it would be two isosceles triangles.
A minimum of 2 triangles are needed, but you can also make a rectangle with 3 or more triangles.
5. 1 rectangle and 4 triangles. The rectangle is known as the base, but it's still a face.
5 faces: 1 rectangle and 4 triangles.
0 (trapezoid, kite, parallelogram) - 4 (rectangle)
