n 1982, mathematician William Wernick published his results on studying triangle constructions with three located points. He defined triangle’s three vertices, three feet of the medians, three feet of the altitudes, three feet of the internal angle bisectors, circumcenter, centroid, orthocenter and incenter as the specific points of a triangle. He used these sixteen points and made a list of one hundred and thirty-nine constructive problems. The term of Euclidean construction is defined in the beginning of this thesis because the solvability of constructive problems depends on the possibility of constructing with ruler and compass. Specific points of a triangle and some of their characteristics have been defined further on. Thesis also includes the solutions of different constructive problems from W. Wernick’s list. The fourth chapter is an overview of an extended list of constructive problems with three located points. To the original list of sixteen points, Harold Connelly has added four extra points, three Euler points and the center of a nine-point circle. By adding these points, W. Wernick’s list has been extended with one hundred and forty new constructive problems. Solutions to some of these problems can also be found in this thesis.
