Answer 2

Answer:

No it is not always necessary for the sum of two angles of a triangle to be greater than than the third angle.

Step-by-step explanation:

For example: Two angles are given 15° and 45° as the angles of a triangle.

Then the sum of the two angles is ,

15°+45°= 60°

Now the other angle of the triangle is,

180°-60°=120°.

So this proves that the sum of two angles must not be always greater than the third angle.
