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 three dimensional triangle is also known as a pyramid. In a triagonal pyramid, there are six edges and four corners.
A triangle consists of three corners and three edges.
if it does have corners its not a triangle
There is not such thing as a three-dimensional triangle. You are thinking of a tetrahedron which is a three-dimensional figure with each side being a triangle. This has four vertices.
A triangles has three sides (also known as edges) and three corners (also known as vertices).
A three dimensional triangle is also known as a pyramid. In a triagonal pyramid, there are six edges and four corners.
3 corners (vertices) and 3 edges (sides).
A scalene (not scaline) triangle (not traingle) has three corners.
A triangle consists of three corners and three edges.
All triangles have three sides and three corners
if it does have corners its not a triangle
There is not such thing as a three-dimensional triangle. You are thinking of a tetrahedron which is a three-dimensional figure with each side being a triangle. This has four vertices.
there are three acute angles in an acute triangle, because there are three corners.
A triangles has three sides (also known as edges) and three corners (also known as vertices).
There are three angles, three sides, and three corners. Tri means three.
all triangles have three corners. An isosceles triangle also has two sides and atwo angles that are equal.
An Isosceles triangle, like all triangles has three vertices (corners).
