Prove that Sum of angles in a triangle is 180° | Angle Sum Property of a Triangle

Download Notes

Do you know why the sum of interior angles of a triangle is 180°? In this video, we are going to discuss the same topic based on angle property of a triangle. Here the theorem is: "The sum of angles of a triangle is 180°." You will get the proof of this theorem in this video. First of all we have to introduce one line at any vertex of a triangle. Due to this, alternate interior angles will form. Also at the same vertex, we will get staright angles whose sum will be 180°. Finally, comparing the equations we will get the desired proof for our theorem. Check out the Video and comment your doubts.
