Friends,
This is a Math video. This is our tenth webisode (WB-10) on "Series 6 -- Lines and Angles".
In this video, we learn that sum of all angles in a triangle is 180°. We know that a triangle has three sides and three vertices. We also know that there are three interior angles in a triangle.
Here, in this presentation, we see that no matter how we draw our triangle, sum of all the three angles in a triangle will always be 180°. We prove this theorem.
This video is suited for class-9 (Class-IX) or grade-9 kids.
Cheers,
Friends at Rising Pearl
prepare it
this was come in my half yearly exam
Hi Shahnaz, Hope the video helped out and you did well in your exam. Cheers,

Hi Shahnaz,
Pls check out new playlists that contain all videos for Class-9 Math for Numbers, Polynomials, Coordinate Geometry, Linear equations, Intro Euclid's geometry, Lines and Angles, Traingles, Quadrilaterals, Areas of Parallelograms and more. Hope you like the videos. When you get a chance, pls do share your feedback. It would be great to hear from you. Thanks! Cheers,
Hi Shahnaz,
I wanted to share that last month, I have launched a new website called dailymathpro.com/.
I post one new Math question everyday. Anyone can answer the question in the comments section. Everyone is encouraged to do so. It is free to use and no registration is required.
The very next day, I post the answer to the previous day's question and the new question for that day.
This will greatly benefit anyone who is interested in Math and is preparing for competitive exams. The questions are designed to make student think outside the box.
Pls do check it out as you may find them helpful.
Cheers,
Suppose that if we have to prove it for our project, then which one we'll write process 3 or 4

Thanks for Helping me
Is it necessary that the theorem should be prove similar to textbook
Hi Joyitka, What is important is that you learn and understand the theorem. There can be more than one way to prove a theorem. You can choose any of right ways you like. Cheers,

can you use the proof to a two column chart proof?
Rea, Can you pls elaborate on your question? Cheers,
In our subject, in proving theorems we use 2 column chart. The thing that contains in the left are the Statements and the right part is the reasons why you used that statement.
Amazing concept sir
Thnx
