3 corners (vertices) and 3 edges (sides).
A three dimensional triangle is also known as a pyramid. In a triagonal pyramid, there are six edges and four corners.
A triangle has 3 sides (or edges) and 3 corners (or angles)
A triangle consists of three corners and three edges.
3
It has 4 corners.
A triangle has 3 sides (edges) and three vertices (corners)
First, I'm assuming the by corners, you mean verticies. Second, the answer depends on what you mean by "three dimensional triangle. To some, this could be interpreted as a pyramid. However, I think it is more likely that you are referring to a triangular prism- a prism shape with a triangle as each base. In this case, there are six "corners". Each side has three, where the length-wise edges of the prism intersect the verticies of the triangle. There are three corners on each side, for a total of six. If you really meant a pyramid, then there are five corners.
A triangular-based pyramid has 4 corners, 4 faces and 6 edges.
An equilateral triangle has sides and angles. There are 3 sides in any triangle. Edges are in three dimensional figures.
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).
A triangles has three sides (also known as edges) and three corners (also known as vertices).
8 edges, 4 corners or vertices and 6 faces! :) * * * * * Not true. A rectangle is a 2-dimensional shape. It has four sides and four vertices (corners).
