With the angles given below, in which case the construction of triangle is possible?
(a) 30°, 60°, 70°
(b) 50°, 70°, 60°
(c) 40°, 80°, 65°
(d) 72°, 28°, 90°

Solution

Correct option: (b)
(a) Sum = 30° + 60° + 70° = 160^o
This is not equal to the sum of all the angles of a triangle.
(b) Sum = 50° + 70° + 60° = 180^o
Hence, it is possible to construct a triangle with these angles.
(c) Sum = 40° + 80° + 65° = 185^o
This is not equal to the sum of all the angles of a triangle.
(d) Sum = 72° + 28° + 90° = 190^o
This is not equal to the sum of all the angles of a triangle.
