The modern answer is that if the shape only fits once onto the original when rotated 360o it has no rotational symmetry.
A right triangle only fits once when rotated 360o so it has no rotational symmetry.

What rotational symmetry does a right-angled triangle have?
I think none. In fact the only triangle that I believe has any rotational symmetry is an equilateral triangle.
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.
What is the order of rotational symmetry of a right angled triangle?
None.
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
Does a right triangle have lines of symmetry Rotational symmetry?
Not necessarily, except rotational symmetry of order 1.
What rotational symmetry does a right-angled triangle have?
I think none. In fact the only triangle that I believe has any rotational symmetry is an equilateral triangle.
What figure does not have rotational symmetry?
a right triangle
Does a right angled triangle have rotational symmetry?
No.
What rotational symmetry does a right angled triangle have?
None.
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.
Does an isosceles triangle have any rotational symmetry?
An isoceles triangle does not have rotational symmetry.
What classification of triangle has both line symmetry and rotational symmetry?
Only an equilateral triangle has rotational symmetry.
What is the order of rotational symmetry of a right angled triangle?
None.
