It has one vertical line of symmetry
yes the number 8 has a vertical line of symmetry. and depending on how you draw it also a horizontal line of symmetry.
Yes, it has one line of reflective symmetry. But the Roman 3 has two lines.
It not just has a line of symmetry; a perfect circle has an infinite number of lines of symmetry.
It has one line of vertical symmetry
An isosceles triangle for example has only one line of symmetry
The number of lines of symmetry in a polygon corresponds to the number of sides it has. If a polygon has n sides, then its symmetry will be n lines of symmetry and it will have one point of symmetry. A pentagon has five lines of symmetry, nonagon has 9, n-gon has n lines of symmetry, so on and so forth.
a shape with a line of symmetry
A cardioid has 1 line of symmetry.
-3
Isosceles triangle, kite. -improvement: an isosceles triangle actually has three lines of symmetry, equal to the number of sides. It is easy to design irregular polygons with an odd number of sides that have just one line of symmetry. A parabola. Many more functions that are more complex - cardioid, for example.
Only One Line of SymmetryAn isosceles triangle only has one line of symmetry.
