Question

prove that sum of all angle of triangle is 180 degree

Answer 1

so, you can understand the proof as given above.

Answer 2

Answer:60° + 60° + 60° = 180°

Step-by-step explanation:

1st angle = x

2nd angle = x

3rd angle = x

= x + x + x = 180°

= 3x = 180°

= x = 180° ÷ 3

= x = 60°

Thus, 60° + 60° + 60° = 180°
