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 naturally occurring substance is found in nature without human intervention, such as minerals or plant extracts. A synthetic substance is artificially created through chemical reactions or processes in a laboratory, like plastics or pharmaceutical drugs.
A crystal of sodium chloride - common salt.
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.
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
