Side BC is smallest and AB is the largest.
GIVEN
Triangle ABC, angle A=30 degree and angle B=60 degree.
TO FIND
The shortest side and longest side of the triangle
SOLUTION
The above problem can be simply solved as follows;
Angles of the triangles are as follows;
∠A = 30°
∠B = 60°
∠C = 180 - (∠A + ∠B)
∠C = 180 - (90)
∠C = 90°
Now,
∠A < ∠B < ∠C
∠C is the greatest angle and ∠A is the smallest.
Since, The side opposite to greater angle is larger and the side opposite to smallest angle is smallest
Therefore,
BC < AC < AB
Hence, Side BC is smallest and AB is the largest.
