One face of a pyramid is a decagon. The number of edges in a decagonal pyramid is?
Twenty edges
A shape with 10 edges?
If it lies in a plane, it is a decagon.
Which 2D shape has 10 straight edges and 10 vertices?
it is a decagon
How many angles does a decagon have?
A decagon has 10 angles (and sides)
How many vertices and angle does decagon have?
A vertex is the same as an angle. A decagon has 10.A vertex is the same as an angle. A decagon has 10.A vertex is the same as an angle. A decagon has 10.A vertex is the same as an angle. A decagon has 10.
How many faces and edges does a decagon have?
1 face 10 edges
How many edges on a decagon?
10 sides and 10 angles
Which shape has 10straight edges?
A regular decagon
What polygon is a shape that has ten edges?
decagon
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 is the shape with 9 edges?
a nonagon a shape with nine edges is called a nonagon. just like pentagon and decagon a shape with nine edges is called a nonagon. just like pentagon and decagon
What shape has ten edges?
A decagon is a shape that has ten edges. DEC means TEN.
One face of a pyramid is a decagon. The number of edges in a decagonal pyramid is?
Twenty edges
A shape with 10 edges?
If it lies in a plane, it is a decagon.
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.
Which 2D shape has 10 straight edges and 10 vertices?
it is a decagon
How many faces sides and vertices does a decagonal prism have?
12 faces, 30 edges and 20 vertices. It has 2 decagons plus 10 rectangles between them giving 12 faces It has 2 x 10 vertices on each decagon giving 20 vertices It has 10 edges round each decagon plus another 10 joining the vertices of one decagon to the other decagon's vertices giving 2x10+10 = 30 vertices
