#DWFINITION OF ALTITUDE GEOMETRY HOW TO#

Substituting x into either equation will give us:

Y - 1 = 4/3 * (x - 1) so y = -1/3 + 4/3 * x The altitude of a triangle is a line through a given vertex of the triangle and perpendicular to the side opposite to the vertex. Altitude noun the elevation of a point, or star, or other celestial object, above the horizon, measured by the arc of a vertical circle intercepted between such point and the horizon. A triangle is a closed, 2-dimensional shape with 3 sides, 3 angles, and 3 vertices. The perpendicular foot, also called the foot of an altitude, is the point on the leg opposite a given vertex of a triangle at which the perpendicular.

The equations in the above paragraph may look scary, but you don't need to worry, it's not that difficult! Let's check how to find the orthocenter with an example, where our triangle ABC has the vertex coordinates: A = (1, 1), B = (3, 5), C = (7, 2).
