In 2-d a circle, in 3-d a sphere.
A triangle.
A general (scalene) triangle.
The number of lines of symmetry a shape has depends on its specific geometric properties. For example, a circle has an infinite number of lines of symmetry, while a square has four. A rectangle has two lines of symmetry, and a triangle can have three, two, or none, depending on its type. To determine the exact number for a specific shape, you would need to analyze its symmetry characteristics.
lines of symmetry
Shapes do not always have lines of symmetry. For example, if you have an irregular shape, it will not have a line of symmetry. I am quite certain though that all geometric shapes have a line of symmetry.
Yes, it is possible for a shape to have at least one pair of parallel lines and no lines of symmetry. For example, an irregular trapezoid has one pair of parallel sides but lacks any lines of symmetry due to its uneven angles and side lengths. This demonstrates that parallel lines and symmetry are independent properties in geometric shapes.
Geometric shapes mean that the shape is just a basic shape, like for example, a trapazoid would be a geometric shape because of it continuous lines that connect at each corner.
no shape does! * * * * * Not true. A parallelogram has rotational symmetry of order 2, but no lines of symmetry.
A circle is symmetric about ANY diameter. The number of possible diameters of the same circle is infinite. And on the same principle, a sphere will have lines of symmetry in every direction in 3 dimensions.
a pentagon has 5 lines of symmetry
A hart is a deer. The organ in your chest and the geometric shape are "hearts".The deer and the geometric shape both have 1 axis of symmetry. The organ is asymmetrical.
A 2d shape with uncountable lines of symmetry is a circle.
