No. A wave oscillates at right angles to its direction of propagation and there are plenty of waves in nature: electromagnetic, sonic, in water etc.
Sure. The angles between edges in a salt crystal are right angles. And that's extremely precise. If you're willing to be a bit more wishy washy, you could say that trees stand at right angles to the ground. Humans walk at right angles to the ground as well.
4 right angles, no other angles.
It has 6 angles, none of which are right angles.
Yes, the 4 inside angles are right angles
No, the angles aren't right angles.
A crystal of sodium chloride - common salt.
a naturally occurring substance is one that can be randomized in between matter of existence for example: it is a substance you can create without knowing what it does so it occurs naturally. the synthetic substance is one of which a robot could relate to as it is a type of substance used within robotics and metallics of vehicles and other electrical equipment (synthetic meaning robotic) Firstly synthetic does not mean robotic. Look it up. Secondly I'm not convinced that the answer above would be right even if it was coherent. Naturally occurring denotes a substance that occurs in nature, in the right circumstances this can cover a wide variety of things. Synthetic substances are artificial or man made, generally for a specific purpose. Even some elements can be synthesized though these are incredibly unstable and thus not naturally occurring.

No, it is more correct to say that ammonia may occur most anywhere if the conditions are right.
... right angles, by definition of a rectangle.... right angles, by definition of a rectangle.... right angles, by definition of a rectangle.... right angles, by definition of a rectangle.
A kite has 4 right angles (all angles of the kite are right angles), since the kite is parallel. If the kite was cyclic, then 2 right angles. And if normal kite, then 0 right angles.
Yes, a rectangle has right angles. In fact it has 4 right angles.
4 right angles, no other angles.
It has 6 angles, none of which are right angles.
Yes, the 4 inside angles are right angles
No, the angles aren't right angles.
No, if it has right angles it is a special case, such as rectangle, but in general it does not have to have any right angles
