There are an infinite amount.
rotation symmetry of a parallelogram Sequence
A cone does not have any parallel lines
sqrt(1000) = 31.62... So there are 31 (or 32 including 0 = 02).
Horizontal lines always have a slope of 0.
It can have 0, it can have 8, and some numbers in between.
There are 0 lines of symmetry in a parallelogram.
9
The numbers that typically have two lines of symmetry are 0, 1, and 8. The number 0 has vertical and horizontal lines of symmetry, while 1 has a vertical line of symmetry. The number 8 has both vertical and horizontal lines of symmetry as well. Other numbers like 2 and 5 may have some symmetry but not consistently two lines.
a triangle has 0 lines of symmetry.
0 lines of symmetry
11
A heptagon can have 0, 1 or 7 lines of symmetry.
A triangle can have 0, 1 or 3 lines of symmetry.
for digits 0 to 9 0,1,3,8 have lines of symmtery
A zero technically has an infinite amount of lines of symmetry.
In general, a triangle can have 0, 1 or 3 lines of symmetry.
