A triangle is one of the basic shapes of geometry: a polygon with three corners or vertices and three sides or edges which are line segments. A triangle with vertices A, B, and C is denoted ABC.
the secondary parts are at the bottom.
the secondary parts of the triangle
median - a segment whose endpoints are a vertex of the triangle and the midpoint of the opposite side
angle bisector - a segment which bisects an angle and whose endpoints are a vertex of the triangle and a point on the opposite side
altitude - a segment from the vertex of the triangle perpendicular to the line containing the opposite side
perpendicular bisector - a line whose points are equidistant from the endpoints of the given side.
incenter - the point of concurrency of the three angle bisectors of the triangle
centroid - the point of concurrency of the three medians of the triangle
orthocenter - the point of concurrency of the three altitudes of the triangle
circumcenter - the point of concurrency of the three perpendicular bisectors of the sides of the triangle .

because it is part of geometry
There are four different types of triangles. They include the isosceles triangle, equilateral triangle, scalene triangle and obtuse triangle. Triangles are used in geometry.
There are 3 angle in any triangle. Iin plane geometry. collectively they will add up to 180 degrees. In non-Euclidean geometry the total will be greater or less than 180 degrees depending on which geometry is being used.
In Euclidean geometry a right angle triangle has two acute angles. All others have three.
