What does triangle mean

The geometric shape consisting of the right parts that combine three points that are not on the same line is called triangle. These points are called the internal angle of the corner, the right parts of the edges and the edges. The angle between one edge and the extension of another edge overflowing from the corner is also called an external angle. Any edge of the triangle can be the base. The corner opposite the base is called hill and the angle of the hill angle. The vertical part drawn from the hill point to the base is called height. The right part that combines the midpoint of an edge to the corner opposite the side is called the edge, and the direction that divides the angles in two is called bisector.
