Which of the following pieces of data does not uniquely determine an acute angled 
( R = circum-radius)
A
B
C
D
Text Solution
Verified by ExpertsThe correct answer is:
D
and 
So, two sides and two angles are known. So, 
is known. Therefore, two sides and included angle is known. So, 
is uniquely known in case . If a, b, c are known the 
is uniquely known in case . 
. So, sides a, b and angle A, B are known. So, 
is known. Therefore two sides and included angle is known. So, 
is uniquely known in case .
. So, only a side and an angle is known. So, 
is not uniquely known in case .
