Term similar is more wide than term congruent. For example: if you say that two triangles are congruent that automatically means that they are similar, but if you say that some two triangles are similar it doesn't have to mean that they are congruent.
The width of a rectangle is the same as one of its sides. That is not [usually] the case for a parallelogram.
Yes as would be the case in two similar equilateral triangles.
Given certain triangles, it would be possible for an angle to be bisected and create two new triangles which are similar to each other. And in the case of a [45°, 45°, 90°] right triangle, if you bisect the right angle, then you will create two new [45°, 45°, 90°] triangles (both similar to each other and similar to the original).
If you mean for multiplication, it is because it is a double negative. If you think of the phrase 'I will not not go' you are not *not going* which means you will go. It is a similar case here.
