It depends upon the pyramid:
if it is a right rectangular pyramid it will have one axis of rotational symmetry which runs from the apex to the centre of the base and a rotational symmetry of 2.
If it is not a right rectangular pyramid then there is no axis of rotation which will permit the pyramid to fit on itself before a complete rotation of 360°
The line joining the apex to the centre of the square base of a right pyramid is an axis of symmetry. Not sure what the other three are!
A rectangle has 2 axes of symmetry.
a rectangle has 2 axes of symmetry
It has 5 axes of symmetry
An isosceles triangle definitely has three axes of symmetry
A rectangle has two axes of symmetry and has rotational symmetry of order 2.
It has rotational symmetry of infinite order as well as an infinite number of axes of symmetry.
A hexagon can have rotational symmetry of order 1, 2, 3 or 6.It can have 0, 1, 2 or 6 axes of symmetry.
They both have rotational symmetry - of order 2. But whereas a rectangle has 2 axes of symmetry, a parallelogram has none.
A cuboid has rotational symmetries of order 2 around each of the three axes going through a pair of opposite faces.
A hexagon can have rotational symmetry of order 1, 2, 3 or 6.It can have 0, 1, 2 or 6 axes of symmetry.
The line joining the apex to the centre of the square base of a right pyramid is an axis of symmetry. Not sure what the other three are!
I believe it has both. If you draw planes through the middle of opposite sides e.g. top/bottom, left side/right side, front/back, you will get three planes of (refection) symmetry. Also if you draw three lines through those same points, you will get three axes of (rotational) symmetry.

There are infinitely many axes of symmetry in mathematics.
It has 5 axes of symmetry
