Because the circle's diameter has infinite lines of symmetry
A decagon need not have any lines of symmetry. It can also have 1 or 10 lines of symmetry.
It have 4 axis of symmetry . Two Perpendiculars and two Diagonals
A decagon need not have any lines of symmetry. It can have 10.
10 lines of symmetry
no shape does! * * * * * Not true. A parallelogram has rotational symmetry of order 2, but no lines of symmetry.
Rotational symmetry is based on points of rotation not lines
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.
A tetrad has rotational symmetry of order 4. It also has no lines of symmetry. It is also known as a swastica.
Yes. A circle has infinitely many lines of symmetry and it also has rotational symmetry of infinite order.
