Description:
This video explains very important construction of class IX on how to construct a triangle when a side, a base angle and difference of two sides are given using compass in real time. It is to be noticed that there are two case of constructing a triangle when difference of sides are given. Watch carefully and Do side by side your own construction to gain maximum benefit.
The construction is done using KYAN in live class in distance leaning mode under pandemic COVID situation. When there are lots of online learning taking place around the globe in all subjects, the teaching learning of skill based topics poses challenges before a Maths teacher on HOW to teach CONSTRUCTIONS in real time.
The ultimate solution found was KYAN.
