As can be seen in the illustration below, it is possible to trace four segments in a triangle, each with different characteristics. From these four different types of triangle divisions, we can find four important points in the triangle. The table presents a summary of the main characteristics of these points.

**Altitude**: draw a line at right angles to a side and going through the opposite corner.**Angle bisector**: draw a line from a corner so that it splits the angle in half.**Median**: draw a line from a corner to the midpoint of the opposite side.**Perpendicular bisector**: draw a line at right angles to the midpoint of each side.

Name | Image | Point | Curiosities |
---|---|---|---|

Orthocenter | Intersection point of the 3 altitude. | The orthocenter is in the inner region of the triangle if this is a acute triangle, coincides with the vertex of the right angle if it is a right triangle and lies outside the triangle in the case of this being a obtuse triangle. | |

Incenter | Intersection point of the 3 angle bisector | The incenter is the center of a circle inscribed in the triangle. Therefore, it is at the same distance from all its sides. | |

Centroid | Intersection point of the 3 median | The centroid is the center of gravity of the triangle. If we suspend a triangle through its centroid, it stays in balance. This point is at a distance of two-thirds from the median to the corresponding vertex. | |

Circumcenter | Intersection point of the 3 perpendicular bisector | The circumcenter is the center of a circumference circumscribed in the triangle. Therefore, it is at the same distance from the three vertices. |
