It depends on the type of triangle.
A scalene triangle (no equal sides) has no rotational symmetry.
An isosceles triangle (2 equal sides) has rotational symmetry order 2.
An equilateral triangle (3 equal sides) has rotational symmetry order 3.
The order of rotational symmetry is how many time a shape will fit over itself during one complete rotation.

Does a triangle have a line symmetry rotational symmetry or both?
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.
Can a triangle have rotational symmetry and why?
Yes, an equilateral triangle has rotational symmetry of order 3.
Does an equilateral triangle have rotational symmetry?
yes it does. It a rotational symmetry of 3
How many orders of rotational symmetry does a scalene triangle have?
A scalene triangle has one order of rotational symmetry.
Does an isosceles triangle have rotational symmetry?
An isoceles triangle does not have rotation symmetry
