Triangle: Geography, Appearances & Properties

A triangle or trigon is a polygon consisting of three sides connected at three corners. It is one of the basic shapes in geometry and the simplest of polygons. The corners, also called vertices, are zero-dimensional points while the sides connecting them, also called edges, are one-dimensional line segments. A triangle has three internal angles, each one…

How Triangle connects Entity context

The extracted context around Triangle shows recurring relationship patterns in the source. For example, Triangle → angle that is a linear pair, ellipse inscribed within the triangle tangent to its sides at the contact points of its excircles, figure consisting of three line segments, matter of convention, plane figure and its interior is a planar region, region of a general two-dimensional surface enclosed by three sides that are straight relative to the surface, shape with three curved sides, straight line passing through the midpoint of the side and being perpendicular to it, straight line through a vertex and perpendicular to the opposite side, straight line through a vertex and the midpoint of the opposite side, straight line through a vertex that cuts the corresponding angle in half, triangle not embedded in a Euclidean space, triangle with circular arc edges Another extracted example is Triangle → AB, ABC, CA, Every, Marden's, PA, PB, PC, QA, QB, QC, Steiner, The Mandart. Use these groups to spot repeated connection types before inspecting the individual relationships.
