Astronomical survey
Cadastral survey
Aerial survey
Photogrammetric survey
Assertion (A): In a spherical triangle, the sum of the three sides is always less than the circumference of the great circle.
Reason (R): The sum of the three angles of a spherical triangle is greater than two right angles, but less than six right angles.
Both A and R are true and R is the correct explana-
tion of A
Both A and R are true but R is not a correct expla-
nation of A.
A is true but R is false.
A is false but R is true.
