A pyramid with 20 edges?
There are actually more than a pyramid that have that number of edges. Pentagonal star pyramid has 20 edges. Decagonal pyramid is another one.
How many corners does a Decagonal pyramid have?
By "corners", do you mean vertices or edges?
How many edges vertices faces does a decagonal pyramid have?
20 edges, 11 vertices (corners) and 11 faces.
How many edges does a decagonal pyramid have?
10 I think? * * * * * Sorry, but you think wrong. There are 20.
How many vertices and edges does a decagonal prism have?
Vertices: 20 Edges: 30 Faces: 12

How many edges does a decagonal pyramid?
It has 20 edges.
How many corners for a decagonal pyramid?
A pyramid has one more corner and faces than the number of sides in its base; thus a decagonal pyramid has 10 + 1 = 11 faces and corners. A pyramid has twice as many edges as sides in its base; thus a decagonal pyramid has 2 X 10 = 20 edges.
How many faces vertices and edges does a decagonal pyramid have?
A decagonal based pyramid will have 11 faces, 11 vertices and 20 edges
How many faces edges and vertices does adecagonal?
Not sure what a decagonal is. Since the question refers to faces, edges and vertices, it may be assumed that the object in question is 3-dimensional. A decagon certainly is not, so decagonal cannot be a mistaken name for a decagon.

How many edges vertices faces does a decagonal pyramid have?
20 edges, 11 vertices (corners) and 11 faces.

How many edges on a decagonal prism?
There are 30 edges on a decagonal prism.
How many faces have perpendicular edges in a decagonal based prism?
Assuming a regular decagon is the base of the prism, it would be 10 faces. With an irregular decagon, it is possible that two (or more) of the edges of the decagons are perpendicular, so all 12 faces could have perpendicular edges.
What two polyhedrons have a total of 20 edges?
pentagonal antiprism, pentagonal deltohedron(not deltahedron), decagonal pyramid, and many more.
How many parallel lines in a decagonal prism?
There are 10 parallel lateral edges. And ten parallel edges between the two bases. There could be more - within each decagon, but that depends on the decagons, and details of these are not given.
