sum of the three angles of a triangle is 180 | How to Prove | Theorem | Proof of the Sum of Angles|
This video focuses on proving that the sum of the measure of a triangle is 180 degrees. The Alternate Interior Angles Theorem and the measure of a straight angle is used to prove the proposition that sum of the measure of a triangle is 180 degrees.
To prove this, we
- Draw any triangle
- And mark its angles
- We write Given and to prove
- To prove it, we do some construction
- In this construction, we mark two more angles
- Then we use Linear Pair, Alternate angles to prove this theorem
