How many faces vertices and edges are in a triangle?

Answer 1

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
