Question

2. Can the following angles be the interior angles of a Triangle?
(1) 40°, 70°, 80°
(ii) 20°, 95°, 65°
(iii) 45°, 55°, 80°
(iv) 35°, 45°, 50°​

Answer 1

Answer:

No

Step-by-step explanation:

Because the angle sum property of a triangle is 180°

So, it means that the sum of the interior angles of a triangle should be 180° . Not more than that or not less than 180°

(1) 40 + 70 + 80 = 190° ≠ 180°

(2) 20 + 95 + 65 = 180° = 180°

(3) 45 + 55 + 80 = 180° = 180°

(4) 35 + 45 + 50 = 130° ≠ 180°

So the first one and the last one are wrong.
