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.
If the shape has three straight lines and no other lines then it has to be a triangle
There are 3 lines of symmetry ina 6-sided shape.
hectagon
A hexagon.
None. For a 3-dimensional object, a line of symmetry implies rotational symmetry and an aircraft has no line of rotational symmetry.
An equilateral triangle.
yes 3 fold
An equilateral triangle.
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.
Yes as would be the case in two similar equilateral triangles.
3
An equilateral triangle
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.
there r 3 lines of symmetry in a equilateral triangle
It appears to have 1 line of horizontal symmetry
It depends on the dimensions of the triangle, some have 0, but no triangle will ever have more than 3 lines of symmetry.
