There are infinitely many axes of symmetry in mathematics.
A regular pentagon has five axes of symmetry.
2! A rectangle has only 2 diagonals, one from the corner and the other from the corner. Also that the rectangle has 4 angles, 4 sides, 2 axes of symmetry ( DONT GET CONFUSED)
a rectangle has 2 axes of symmetry

All rectangles have 2 axes of symmetry, which are the lines joined by the two pairs of midpoints of opposite sides.

There are infinitely many axes of symmetry in mathematics.
It has 5 axes of symmetry
A square has 4 axes of symmetry.
A regular pentagon has five axes of symmetry.
An isosceles triangle definitely has three axes of symmetry
Not sure about a duodecagon, but a regular dodecagon has 12 axes of symmetry.
Though an "axis" is not something that is normally associated with a rectangle, a rectangle has an infinite number of axes.
It has two lines of symmetry, one each perpendicular to each other passing thru the center of the rectangle
