Prove that Sum of angles in a triangle is 180° | Angle Sum Property of a Triangle
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.
Proof | Vertically Opposite Angles are Equal to each other.
Angles formed by Parallel lines and Transversal | Geometry
