Triangles are polygons (two-dimensional) . Only polyhedrons have faces, verticles and edges. You could define as triangle as having either one or two faces (top/bottom), three vertices, and three edges.
For pyramids and other polyhedrons, F + V - E = 2
e.g.
- a three-sided pyramid has 4 faces, 6 edges, and 4 vertices.
- a four-sided pyramid has 5 faces, 8 edges, and 5 vertices
Assuming that a solid triangle is a tetrahedron, the answer is: faces: 4 edges: 6 vertices: 4
It has 9 edges, 5 faces and 6 vertices
A triangle has 3 sides, 1 face and 3 vertices.
2 faces, 4 edges, and 4 vertices 2 faces, 4 edges, and 4 vertices
Vertices: 12 Edges: 30 Faces: 20
Faces: 1 Vertices: 3 Edges: 3
9 edges/ 6 vertices/ 5 faces
Assuming that a solid triangle is a tetrahedron, the answer is: faces: 4 edges: 6 vertices: 4
4 faces/ 4 vertices/ 6 edges
5 faces, 6 vertices, and 9 edges.
A triangle has 3 vertices and three sides (edges). It has one face.
5 faces 6vertices 9 edges
it has two faces five vertices and eight edges
Edges: 8 Faces: 5 Vertices: 5
It has 9 edges, 5 faces and 6 vertices
It has 9 edges, 5 faces and 6 vertices
A triangle has 3 sides and 3 vertices. Strictly speaking, the interior of the triangle is not part of the triangle so it has no faces. However, a triangular lamina will have two faces - one from above and one from below.
