There are three methods of displaying triangular shapes from either two or three points.
2 Pt Triangle - This option creates an isosceles triangle from two points which represent its base. The height of the triangle is provided in the Width dimension, normally W=. If the width is positive, the triangle will be created to the right of the two points.
3 Pt Triangle - This option creates a triangle from three points each of which represents one of the apexes of the triangle.
2 Pt Eq Triangle - Creates an equilateral triangle from two points which represent one of the sides. The third apex will be calculated to the right of of the two points.
