How many lines of symmetry does a circular cone have?
If it is a right circular cone, it has an infinite number of planes of symmetry. If it is an oblique circular cone, it has one plane of symmetry.
How many symmetry does a cone have?
A cone has infinitely many symmetries. This is because a cone can be rotated about its axis an infinite number of times and still look the same. Additionally, a cone also has rotational symmetry, meaning that it looks the same when rotated by any multiple of 360 degrees.
Which 3d shape has 3 faces?
There are many possible answers. Some are: A sphere or ellipsoid sliced by two planes A cone sliced by two planes A toroid (doughnut) with a wedge cut out An infinite circular prism sliced by two planes.
Why does a cylinder have one more plane of symmetry than a cone?
A cylinder and a cone have infinitely many planes of symmetry because of the circular face. However, a cylinder can also be cut in half lengthwise (imaging cutting a soda can in half), while a cone cannot (imagine cutting a ice cream cone in half). Therefore, a cylinder has one more plane of symmetry than a cone.
What shape has 2 edges no vertices and no right angles?
A frustum of a cone, or a sphere sliced by two planes are a couple of examples.
