Altitude (Geometry) Definition

In geometry, an altitude for triangles is defined as the line segment leaving from a vertex (forming an angle of 90°) perpendicular to the base (the opposite side) of a vertex. The line between the base and the vertex is known as altitude.

In other words, the altitude in geometry is defined as the length of a triangle from the apex to the base of a triangle.

Every triangle consists of three altitudes, and where the line of each altitude intersects with each other is known as the orthocenter of the triangle.
