A pyramid could have any number of right angles between, and inlcuding, none and 8.
There are no right angles (90 degrees) in a hexagonal pyramid.
four
5 angle in a square pyramid
A square has 4 right angles.
4 right angles
There are no right angles (90 degrees) in a hexagonal pyramid.
A pyramid has 6 angles, 8 faces, and 6 edges. Is that right?
If a triangular based pyramid has any right angles it has three. (Think of the corner of a cube). There are many triangular based pyramids that do not have any right angles.
None normally
It need not have any eg in a tetrahedron.
No angles are larger than 90 degrees in a square based pyramid.
4
Normally four but there could be six if the opposite edges at the apex met at right angles.
A square pyramid has 16 angles.
No but a right angle triangle does
four
Just the one and it is the base face
