There are three straight edges in a triangle.
If the lines are straight then it IS a triangle.
A plane figure with three straight sides and three angles.
A triangle is a two dimensional shape with three straight lines and three vertices. A sphere is a three dimensional object with no straight lines and no vertices and such that every point on its surface is a constant distance from a fixed point. It is not possible to have a triangle sphere.
Three straight lines meeting, pairwise, at three points (vertices).
No. A triangle is a closed shape made of three straight lines, joined at their endpoints forming three vertices and three angles (hence tri-angle).
