Answer :

Final answer:

Knowing the sum of angles in a triangle is crucial in geometry.


Explanation:

The sum of angles in a triangle being 180 degrees is a fundamental concept in Euclidean geometry.

This can be demonstrated through various methods, such as drawing a triangle on a plane and measuring its angles using a protractor. For example, in a triangle with angles measuring 60, 70, and 50 degrees, the total would indeed be 180 degrees.

Understanding this property is essential in various mathematical calculations and proofs involving triangles.
