I am a kid and have no problems with reflective symmetry but some kids might
It could be that some just don't understand it just like You cant teach a 2 year old the Pythagorean therom and have them now what it means
Yes - it has two lines of reflective symmetry.
An octagon has 8 lines of reflective symmetry.
Yes
Scalene
None.
A scalene triangle has no lines of symmetry.
Yes - it has two lines of reflective symmetry.
An octagon has 8 lines of reflective symmetry.
Yes
No but capital E has reflective symmetry
Scalene
it has both reflective and rotational symmetry
There is reflective symmetry about each of the diagonals as well as rotational symmetry or order 2.
Yes you idiot
None.
How about an isosceles trapezoid
Both.
