Edge is probably not the best word to describe it. Planes have zero thickness, and to me the word 'edge' implies something that takes up space. It's something like describing a point as a really, really, really tiny circle. That's not correct; a point has zero area-- not just a tiny bit of area.

How many planes of symmetry does a rectangular pyramid have?
Two.
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.
What are examples of zero dimensional and or one dimensional figures?
zero-dimensional examples: Endpoints of edges (vertices and corners) Zero-dimensional figures lie in two-dimensional planes. one-dimensional examples: Edges of figures (sides and arcs) One-dimensional figures lie in two-dimensional planes.
How many edges in a circle?
An edge is a concept that applies to 3-dimensional objects and is the intersection of two planes that form boundaries of the object. None of these apply to a circle so the answer must be none.
What is a prism in geometry?
A prism is a 3-dimensional shape with the following properties: It has 2 identical, polygonal faces whose planes are parallel. The corresponding edges of the polygons are connected by rectangular faces.
What does the word edges mean in math terms?
Edges are one dimensional objects where two planes meet.
Is a solid bounded by places that intersect in parallel lines called edges and by two parallel planes that cut all the edges?
Not necessarily.
What is edges on a three dimensional figure?
It is the intersection of two planes or the line joining two vertices.
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 curved edges?
A sphere with two slices cut out of it by planes. A torus (doughnut) with a chunk taken out of it.
How many straight sides in a cube?
There are 12 edges on a cube. There are 5 flat surfaces (planes) on a cube as well.
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 are examples of zero dimensional and one dimensional figures?
zero-dimensional examples: Endpoints of edges (vertices and corners) Zero-dimensional figures lie in two-dimensional planes. one-dimensional examples: Edges of figures (sides and arcs) One-dimensional figures lie in two-dimensional planes.
How many planes of symmetry does a rectangular pyramid have?
Two.
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 planes does a regular tetrahedron have?
A tetrahedron is a triangular based pyramid that has 4 faces, 6 edges and 4 vertices
How do you sketch a three planes whose intersection is a point?
If you draw a capital "Y" with say each angle = 120 degrees, then the three lines will represent where the edges of the planes meet each other and the centre point will be the vertex where the three planes intersect. You are basically looking at the corner of a cube at an angle. If you connect the ends of the three lines you will be looking down at a triangular pyramid (three faces with three edges and the vertex in the centre).
