How many symmetry does a cone have?
A cone has infinitely many planes of symmetry because its base is a circle, which also has an infinite amount of planes of symmetry. Prove it by making a 3D model of it and they look at the number of vertexes.
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.
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.

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.
Which shape has edges and no corners?
A section of a cone or spheroid intersected by one or two planes that themselves do not intersect within the solid.A section of a cone or spheroid intersected by one or two planes that themselves do not intersect within the solid.A section of a cone or spheroid intersected by one or two planes that themselves do not intersect within the solid.A section of a cone or spheroid intersected by one or two planes that themselves do not intersect within the solid.
What is the frustum of cone?
It is the section of a cone between two parallel planes that are perpendicular to the axis of the cone. In simpler terms, it is what is left of a solid cone when the pointed end is cut off.
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.
What has 1 curved face and 2 flat face?
There are many possible answers.For example, a sphere or a cone intersected by two planes.
What solid has three faces two edges and no vertices?
Many solids. Some are: A sphere intersected by two planes, An ellipsoid intersected by two planes, Any blob intersected by two planes, A toroid (doughnut) with a wedge removed, A double-cone intersected by two planes, A cylinder.
What shape has 2 edges and no vertices?
There are many possible answers: A cylinder A cone sliced by two planes perperndicular to its axis A toroid (doughnut) sliced by a plane vertical to its axis. A sphere sliced by two planes An ellipsoid sliced by two planes A paraboloid sliced by two planes etc.
What 3d shape has 0 vertices 2 edges and 3 faces?
If they are all plane faces then there is no such figure. Otherwise it could be a sphere intersected by two planes, an ellipsoid intersected by two planes, a cone intersected by two planes, or one of several other shapes.
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.
Which shape has curved and flat faces?
There are infinitely many. For example, any sphere, ellipsoid, cone, toroid, cordoid etc that is intersected by one or more planes.
What is a binode?
A binode is a double point of a surface whose tangent cone consists of two different planes.
