ABEAM
Yes, the 4 inside angles are right angles
It has 6 angles, none of which are right angles.
4 right angles, no other 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.
Yes, the 4 inside angles are right angles
No, the angles aren't right angles.
The bilge keel is fitted at right angles to the bilge radiused plating but does not extend beyond the extreme breadth line . It positioned after model test to ensure minimum resistance to forward motion of ship .
