Скачать или смотреть Theorem related to Angles in a Circle I / WBBSE X

This is an educational video for learning purpose.

This is the first video of the lesson series on circles. In this video we will prove the theorem which states that “the angle subtended by an arc of a circle at the centre is double the angle subtended by it at any point on the remaining part of the circle.”

The proof of the result:
The exterior angle of a triangle is equal to sum of its opposite interior angle👇
👉    • Class 7 ICSE / TRIANGLE AND ITS PROPERTIES...  

The angle opposite to equal side of an Isosceles are equal.
