1. Triangle

   A triangle is a polygon with three edges and three vertices. It is one of the basic shapes in geometry. A triangle with vertices A, B, and C is denoted △ A B C {\displaystyle \triangle ABC} . In Euclidean geometry, any three points, when non-collinear, determine a unique triangle and simultaneously, a unique plane (i.e. a two-dimensional Euclidean space). In other words, there is only one plane that contains that triangle, and every triangle is contained in some plane. If the entire geometry is only the Euclidean plane, there is only one plane and all triangles are contained in it; however, in higher-dimensional Euclidean spaces, this is no longer true. This article is about triangles in Euclidean geometry, and in particular, the Euclidean plane, except where otherwise noted.

1. triangle

   A triangle is a polygon with three edges and three vertices. It is the simplest possible polygon. The sum of the internal angles in a triangle always equals 180 degrees. Triangles can be classified based on the relationship of their sides and angles such as equilateral (all sides are equal), isosceles (two sides are equal), scalene (no sides are equal), right-angled (one angle is a right angle), obtuse (one angle is greater than 90 degrees), and acute (all angles are less than 90 degrees).
