a rectangle has 2 axes of symmetry
only when the rectangle is a square
Yes. In 3 dimensions, a rectangle has 3 C2 axes perpendicular to each other and an inversion center at the center of the rectangle. There are also reflection planes along each of the C2 axes; this makes the point group of the rectangle D2h.
It has 5 axes of symmetry
An isosceles triangle definitely has three axes of symmetry
a rectangle has 2 axes of symmetry
No but a rectangle does have 2 lines of symmetry
A rectangle has two axes of symmetry and has rotational symmetry of order 2.
only when the rectangle is a square
Only when the rectangle is a square.

You are a rectangle
False
All rectangles have 2 axes of symmetry, which are the lines joined by the two pairs of midpoints of opposite sides.
They both have rotational symmetry - of order 2. But whereas a rectangle has 2 axes of symmetry, a parallelogram has none.
Yes. In 3 dimensions, a rectangle has 3 C2 axes perpendicular to each other and an inversion center at the center of the rectangle. There are also reflection planes along each of the C2 axes; this makes the point group of the rectangle D2h.
There are infinitely many axes of symmetry in mathematics.
