Answer 2

Answer:

63° + 37° + 80° = 180

or

45° + 45°+ 90° = 180

Step-by-step explanation:

(i) 63° + 37° + 80° = 180° Angles form a triangle

(ii) 45°, 61°, 73° is not equal to 180° Therefore not a triangle

(iii) 59°, 72°, 61° is not equal to 180° Therefore not a triangle

(iv) 45° + 45°+ 90° = 180° Angles form a triangle

(v) 30°, 20°, 125° is not equal to 180° Therefore not a triangle
