Not necessarily, except rotational symmetry of order 1.
A triangle........I think
Scalene triangle * * * * * A scalene triangle does not have rotational symmetry of order 3. The triskelion (the three legs) on the Isle of Man flag, or a simplified version of that shape will meet the requirements.
Rotational symmetry refers to symmetry of the figure when it is rotated about a single point in the same plane. Lines of symmetry apply to reflections. You do not have lines of rotational symmetry.
Yes, the capital letter N has rotational symmetry but no lines of symmetry:
First of all, your grammar is terrible. The question should be "Does a triangle have 2 lines of symmetry and 2 lines of rotational symmetry? and the answer is no. A triangle can not have 2 lines of rotational symmetry, because you only rotate the image, you do not use any lines.
Rotational symmetry is based on points of rotation not lines
Triangle * * * * * The only triangle with rotational symmetry of order 3 is an equilateral triangle and that has 3 lines of symmetry, not 0. The triskelion (the three legs) on the Isle of Man flag has rotational symmetry of order 3 but no lines of symmetry.
Not necessarily, except rotational symmetry of order 1.
how many lines of symmetry has an equilateral triangle
None.
A triangle........I think
The shape that has no lines of symmetry and rotational symmetry order 4 is a scalene triangle. A scalene triangle is a triangle with three unequal sides and three unequal angles. It does not have any lines of symmetry because its sides and angles are not equal, and it has rotational symmetry of order 4 because it looks the same after being rotated by 90, 180, or 270 degrees.
