Use a ruler, protractor and a pair of compasses to construct a triangle accurately. After the triangle has been constructed, leave the construction lines visible so each stage of the process is shown ...

Triangles and other shapes can be accurately constructed using a protractor, a pair of compasses and a ruler. Make an accurate drawing of a triangle with lengths 4 cm and 6 cm with an angle of 40° in ...

Abstract: An algorithm for fast constructing Delaunay triangulations was proposed. In iterations, this algorithm is to select the leftmost one point lying right some convex edges from set of points.
