collinear
In geometry, collinearity of a set of points is the property of their lying on a single line
point of concurrency
In geometry, three or more lines in a plane or higher-dimensional space are said to be concurrent if they intersect at a single point
obtuse
In planar geometry, an angle is the figure formed by two rays, called the sides of the angle, sharing a common endpoint, called the vertex of the angle
exterior angle
In geometry, an angle of a polygon is formed by two sides of the polygon that share an endpoint
constructing triangles
Compass-and-straightedge construction, also known as ruler-and-compass construction or classical construction, is the construction of lengths, angles, and other geometric figures using only an idealized ruler and compass
orthocenter
In geometry, an altitude of a triangle is a line segment through a vertex and perpendicular to a line containing the base
