Answer 1

hey the answer is ....

lets check it out by doing an activity --

cut the angles 1 2 3

and place them as shown


hence angles 1 + 2 + 3 = 180

hope it helps uu frnd.

Answer 2

Hey here's your answer

Given- all angles in a triangle is 180degree.

To prove- all angles are 180 degree

We know that triangle has 3 sides

So,

We take 1st side be- a

" " 2nd " " - b

" " 3rd " " - c

So, a+b+c/3= 180degree

180/3=60

A=60

B=60

C=60

60+ 60+ 60 = 180degree

Hence proved

Hope it helps
