Abstract

This article provides proofs and presents main theorem-related problems concerning the angle between the bisector and the height drawn from the same vertex. The article solved problems that correspond to the theorems related to this angle and explores the "geography of the angle" between the bisector and the height drawn from a single vertex within a circumscribed circle. The triangle construction problems with an element of this angle are designed for students studying geometry in advanced mathematics classes, as well as for mathematics teachers. This article introduces a new formula that has not been published anywhere before. It offers value with new problems, the opportunity to become familiar with the element of a triangle formed by the bisector, and the height drawn from the same vertex.
