Class 9 | NCERT EX 11.2 | Construction of a Triangle | CASE: Sum of two sides
Time
0:25 Construction of 75 degree angle 6:35 Perpendicular Bisector of a line segment 16:25 Construction of an Equilateral triangle 24:25 Construction of a triangle when a side, a base angle and sum of two sides are given
Description:
This video explains very important construction of class IX on how to construct a triangle when a side, a base angle and sum of two sides are given using compass in real time.
It also has construction of 75 degree angle, construction of perpendicular bisector of a line segment, construction of an equilateral triangle.
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.
