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.
"How are straight angles different from right angles?" Is this a statement?
Modern Submarines do not have a keel like other ships....
figure heads
It keeps the keel side down, and can compensate for an uneven cargo load.
A keel has nothing to do with the latitude.A keel does two things:structurally, it acts as the spine(or the breastbone) of the ship to tie the crosswise "ribs" together and provide strength.If the keel is seen on the outside of the hull as a fairly narrow ridge running fore-aft, it'll also help the boat stay on course. This is particularly important for sailing ships, for which the wind will try to push them sideways.Smaller yachts and sailboats can have a fin-like keel sticking straight down instead of a long ridge.Even smaller boats will have a daggerboard doing the same service

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.

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
