Abstract

top
In the first part of the article the proof of the following theorem is given: Let point S be the middle of A B in the triangle A B C , point O the intersection of A B and the axis of angle A C B , point P the foot of the perpendicular from C on A B . If angles A C S , S C O , O C P , P C B are equal, then the angle B C A is the right one. In the second part, the area of right angle triangle using only the length of the axis of the right angle and of the median is derived.
