Just moving a triangle, or rotating, or even reflecting (without scaling) a shape will not change its area or its perimeter.
The rigidity of the triangle derives from the fact that you cannot change any angle in a triangle without also changing the length of at least one side; in any other type of polygon, it is possible to alter the angles of the polygon without changing the lengths of the sides. So if you have a physical object in the form of a triangle, the sides are not going to change their length unless you break them. Other shapes can fold up, but triangles won't.
The two are not directly related. You can change the amplitude without changing the wavelength, and vice versa.The two are not directly related.

As written, that's confusing. The length and width of a triangle wouldn't have any bearing on the perimeter and area of a rectangle unless they overlap in some drawing that only you are looking at. Let's assume you meant rectangle all along. If the dimensions of a rectangle increased 4 times the perimeter would also increase 4 times. The area would increase 16 times. Try it out. A 2 x 3 rectangle has perimeter 10 and area 6. An 8 x 12 rectangle has perimeter 40 and area 96.
No, it does not.
The answer depends entirely on how the dimensions change. It is possible to change the dimensions without changing the perimeter. It is also possible to change the dimensions without changing the area. (And it is possible to change the area without changing the perimeter.)

No. It is possible to change direction without changing speed. However, it is not possible to change direction without changing velocity.
I suppose you could turn it over on its side where one of the legs becomes the base.
No. A rectangle of 1 x 3 has the same perimeter as a rectangle of 2 x 2, but the areas are different.

yes
Given unchanging lengths of the sides, a triangle cannot change its shape. But given unchanging lengths of the sides of a rectangle, it can change its shape by some force by changing its angle measurements. If a 2d load were put on a rectangle, enough force could squish the rectangle into a parallelogram, whereas a triangle cannot change shape without changing the lengths of its sides or bending its sides out of shape (most likely into a curve).Given these properties, a rectangle can collapse its shape much more easily and is flimsy compared to a triangle.
