A triangular pyramid, or tetrahedron, has 4 vertices and 6 edges.
A three dimensional triangle is also known as a pyramid. In a triagonal pyramid, there are six edges and four corners.
6 edges and 4 vertices
A triangular-based pyramid has six edges: three in the base triangle and three from there to the apex.
A triangle based pyramid has 6, a square based pyramid has 8.
A triangular-based pyramid has 4 corners, 4 faces and 6 edges.
A pyramid with an n-sided base will have n + 1 vertices, n + 1 faces, and 2n edges. 6 edges
5 faces 8 edges 5 corners (vertexes) * * * * * Wrong! The answer given above is for a SQUARE based pyramid. A triangle based pyramid, or a tetrahedron, has 4 faces, 6 edges and 4 corners (vertices).
four
4 faces/ 4 vertices/ 6 edges
It has 4 corners.
A triangular-based pyramid has six edges: three in the base triangle and three from there to the apex.
