Sum of angles of a triangle using GeoGebra (Method-2)/त्रिभुजका कोणहरुको योगफल जियोजेब्रामार्फत्

Hello namaskar
It's me, YP Joshi, a mathematics teacher, educator and learner. I am keenly interested to learn mathematics and share my ideas and experiences of teaching and learning with others. I have planned to share all of my knowledges that I have learnt and experienced with all those who are interested to learn. I am hopeful that my experiences and learning will be helpful to many of the students, learners and teachers.
This video helps you to verify experimentally that the sum of angles of a triangle is always equal to two right angles. It is the second method to verify the property as I have already made the previous video to verify it in a different way. This video will be useful to all the learners who are interested in mathematics and technology.
Note: Type Alt + A for alpha, Alt + B for beta, Alt + D for delta, Alt + G for gamma, Alt + T for theta, Alt + S for sigma and so on........
Thank you so much!
