Concurrency of the altitudes of a triangle
Mathematische Semesterberichte, 2013Of all the traditional (or Greek) centers of a triangle, the orthocenter (i.e., the point of concurrence of the altitudes) is probably the one that attracted the most of attention. This may be due to the fact that it is the only one that has no exact analogue for arbitrary higher dimensional simplices, for spherical and hyperbolic triangles, or for ...

Integer Sided Triangles Whose Ratio of Altitude to Base is an Integer
1993For centuries, mathematicians have been fascinated by the special properties associated with right, acute and obtuse triangles and yet new results continue to arise. See references [1] to [6]. The purpose of this article is twofold. We shall first present some additional interesting facts about triangles.

Triangles from sums of altitudes and sides
Far East Journal of Mathematical Sciences, 1998We improve the result by Vajaitu which says that sums of sides and corresponding altitude of a triangle are always sides of a triangle.

Measuring the Speed and Altitude of an Aircraft Using Similar Triangles
SIAM Review, 1991In this note a simple and sometimes practical method is devised with which the average speed and the cruising altitude of an aircraft in flight can be computed from a window seat inside the aircraft. No knowledge of the mechanical structure of the vehicle is assumed.
