An edge.
An edge is the the answer
Edge. (:
They meet at an edge
no that's a vertex a line segment is a straight line between two points that stop completely
'Enneahedron' - a solid figure with nine faces
A solid figure with twenty faces is called an Icosahedron.
were two or more faces of a solid figure
Hexahedron
Polygonal faces.
No.
A decaredra is the ten face solid figure.
Where two faces meet on a 3D figure is called an edge. An edge is the line segment that connects two vertices, which are the points where the faces intersect. In polyhedra, edges play a crucial role in defining the shape and structure of the figure. Each edge is shared between two adjoining faces, contributing to the overall geometry of the solid.
