Tool: Altitude (of a triangle)

Altitude[A,B,C, m] [math]\;\;[/math] A,B,C three points in space, [math]\;\;[/math] m a margin for the base line gives -the altitude from C onto AB, -the base point of the altitude, C' -the (right) angle ∡CC'A -base segment ABC' containing all three points Construction: [url]http://www.geogebratube.org/material/show/id/87370[/url] ____ Of particular interest to me in this construction were obtaining: 1. The altitude never floats in space; AB is extended to meet it. 2. [b]∡CC'A is correct.[/b] (the angles offered by the perpendicular bisector tool are pretend).
