Question

prove that some of all interior triangle angle always180 degree​

Answer 1

Answer:

Let all the three angles be X (Same Variable)

Angle Sum Property of Triangle is 180 Degrees

X + X + X = 180

3X = 180

Transporting 3 to other side,

X = 180/3

X = 60 degrees

So, Each side of a triangle is 60 Degrees

Answer 2

Answer:

try making a triangle and mark three angles as 60degrees each and use angle sum property of triangles and add them all the sum will be 180 degrees

hence proved
