It is the construction of geometrical objects, and it is an essential branch of geometry. Geometry allows us in determining how the shapes and figures fit together to maximize efficiency and visual appeal. The concepts covered in this chapter include: Construction of a Line Parallel to a Given Line, Through a Point Not on The Line, Construction of Triangle, Constructing a Triangle When the Lengths of its Three Sides are Known (SSS Criterion), Constructing a Triangle When the Lengths of Two Sides And The Measure of The Angle Between Them Are Known (SAS Criterion), Constructing a Triangle When The Measures of Two of Its Angles and The Length of The Side Inclined Between Them Is Given (ASA Criterion) and Constructing a Right-Angled Triangle When The Length of One Leg and Its Hypotenuse are Given (RHS Criterion)
