umm... the triforce.
It's very difficult to determine an answer, sincethere is no such thing as a rectangular triangle.

There is no such thing as a milemeter. Assuming you meas millimetres, there is no answer possible because it will depend on the shape and size of the triangle as well as what characteristic of the triangle is being measured.
There is no such thing, the smallest amount of sides a shape can have is 3 (Triangle).
A Right Triangle or sometimes called a Right-angled Triangle has one angle = 90 degrees
No, but there are the Koa'ki Meiru cards, they have 3 red dragons in the shape of a triangle on them.
There is no such thing as a 3d triangle. A 3d shape which has only equilateral triangular faces can be a tetrahedron which has 4 faces or an icosahedron which has 20.
A quadrilateral shape has four sides and four internal angles. A triangle has three sides and three internal angles. Therefore there is no such thing as a quadrilateral triangle.
It depends on what kind of shape it is. if it is a triangle, cut the shape in to two triangles, then find the square foot, if it is a quatrilateral, do the same thing.
No; there is no such thing as a cutie triangle.
By definition, there is no such thing as a triangle with 100 sides. A triangle has exactly three (straight) sides; no more and no less. Having three sides means that the shape also has three internal angles and this explains the name.
