How many corners does a octagonal pyramid have?
nine vertices
An octagonal pyramid has nine vertices; eight are located where the triangular faces meet the base and the ninth is the point at which all of the triangular faces meet at the top of the pyramid. We often call the vertex on top the apex of the pyramid.
How many faces vertices and edges does a octagonal pyramid have?
Answer: An octagonal pyramid has nine faces: eight are triangular faces and one face is a regular octagon. It also has 23 edges and nine vertices.
What’s the angle of an octagon?
135 degrees
An octagon contains six triangles, or 1080 degrees. This means with 8 angles, each angle is 135 degrees.
