Algebra in the Service of Geometry: Can Euler's Line Be Parallel to a Side of a Triangle?.
, 2000A student asked whether other cases occurred or the past several years, I have included a study of Euler's line-the collinearity of the circumcenter, centroid, and orthocenter of a triangle-in my geometry classes. One of the theorems that we prove states

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.

SIMULTANEOUS POSITION LINES FROM ALTITUDE AND AZIMUTH OBSERVATIONS
, 1974Semi-graphic methods for the evaluation of observations in geodetic astronomy generally employ approximate initial values for the unknown position of the observer, and make use of the measurement of one part of the celestial triangle at a noted instant ...

In this study I have used a theoretical framework integrating the theory of Fischbein and the theory of Shulman for examining the algorithmic knowledge of teachers. This framework has shaped the approach to both the formal and algorithmic aspects of knowledge, with reference to several components included in mathematical knowledge as well as ...
