Answer: Option A. -> One
:
A
Sum of interior angles in a tringle = 180∘.
An obtuse angle measures more than 90 degrees but less than 180 degrees.
A triangle can have only one obtuse angle because if there were two obtuse angles, then the sum of two obtuse angles would always begreater than 180∘.
Hence, a triangle can have only one obtuse angle.

Answer: Option D. -> 360∘
:
D
A minute hand of a clock makes a complete revolution in one hour. That is, it turns 360∘ in one hour.

Answer: Option D. -> 80∘,40∘,60∘
:
D
We know that " Sum of interior angles of a triangle =180∘
80∘+40∘+60∘=180∘.
The sum of angles in all the other sets is more than 180∘
∴80∘,40∘,60∘ is the correct option.

Answer: Option B. -> Lines having a uniform distance between them and never meet each other.
:
B
Parallel lines are lines having a uniform distance between them (equidistant) and this distance is constant throughout and never meet each other.

Answer: Option D. -> Reflex angle
:
D
A Straight angle = 180∘
An Acute angle is less than90∘
An obtuse angle is more than 90∘but less than180∘
A Right angle = 90∘
Reflex angle is the only angle which is greater than 180∘ and less than 360∘
