how to construct an angle of 60° #how to construct an angle of 30° #how to construct an angle of 45° #how to construct an angle of 90° #how to construct an angle of 120° #an angle which is a multiple of 15 (ex 45°,60°,150°etc)can only be constructed with tge help of compass #angles which are not the multiple of 15 (ex 55°,65°,79°185°etc) can be drawn with the help of protractor #how to construct a triangle #if 3 sides are given #how to construct an arc #what is radius #arc is a part of a circle #triangld is a simple closed polygon with three sides,three angles #6elements of a triangle are - 3sides and 3 angles #angle is formed when two rays meet at the same point,which is called Vertex of the angle so formed #rays are called Arms of the angle Practical geometry Construction of triangles 15.1 • CONSTRUCTIONS | PRACTICAL GEOMETRY | CLASS... 15.2 • CONSTRUCTIONS | PRACTICAL GEOMETRY | CLASS... 15.3 • CONSTRUCTIONS | PRACTICAL GEOMETRY | CLASS... 15.4 • CONSTRUCTIONS | PRACTICAL GEOMETRY | CLASS... 15.5 • CONSTRUCTIONS | PRACTICAL GEOMETRY | CLASS...
