2. Point of Concurrency
The point of intersection of concurrent lines, ray, or segments is called the point of concurrency

3. Perpendicular Bisector

11. Altitude
An altitude of a triangle is the perpendicular segment from a vertex to the opposite side or to the line that contains the opposite side.

12. Orthocenter
The point at which the lines containing the three altitudes of a triangle intersect is the orthocenter of the triangle
