Question

In each of the following, the measures of three angles are given. State in which cases the angles can possibly be those of a triangle: (i) 63°, 37°, 80° (ii) 45°, 61°, 73° (iii) 59°, 72°, 61° (iv) 45°, 45°, 90° (v) 30°, 20°,125.

​

Answer 1

Answer:

answer is option 1

total measure should be 180

so, 63+37+80=180

I hope this would help you

Answer 2

(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°
