In the video below, we will explore various problems for finding missing side lengths and angles given medians and altitudes.Īlso, will determine the coordinate of the centroid given three vertices, and learn the distinguishing characteristics between perpendicular bisectors (circumcenter), angle bisectors (incenter), medians (centroids), and altitudes (orthocenter). Altitude is also used in the study of three-dimensional geometry, where it refers to the perpendicular distance between a point and a plane in space.

Point O is the orthocenter of triangle ABC. The following theorem can now be easily shown using the AA Similarity Postulate. Check out the example in the picture below, where the white dotted line drops down from the vertex of the triangle to the opposite side and how it forms a 90-degree angle represented by the white square.

Looking at the figure above, the altitudes AD, BE, and CF intersect, or are concurrent, at point O. Figure 1 An altitude drawn to the hypotenuse of a right triangle. An Altitude is a perpendicular line drawn from the vertex of a triangle to the opposite side, creating a 90º angle (or right angle).
