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
