I think none. In fact the only triangle that I believe has any rotational symmetry is an equilateral triangle.
An equilateral triangle has both line symmetry and rotational symmetry. A non-equilateral isosceles triangle has line symmetry but not rotational symmetry. A scalene triangle has neither kind of symmetry.
Yes, an equilateral triangle has rotational symmetry of order 3.
yes it does. It a rotational symmetry of 3
A scalene triangle has one order of rotational symmetry.
An isoceles triangle does not have rotation symmetry

An isoceles triangle does not have rotational symmetry.
Only an equilateral triangle has rotational symmetry.
Yes, an equilateral triangle has rotational symmetry of order 3.
An equilateral triangle has rotational symmetry (order 3).
It is an equilateral triangle which has rotational symmetry
yes it does. It a rotational symmetry of 3
Equilateral triangles have rotational symmetry.
triangles have 0 rotational symmetry
It does have rotational symmetry of order three.
A scalene triangle has one order of rotational symmetry.
An isoceles triangle does not have rotation symmetry
