Question

Two angles in an isosceles triangle can be 60 and 70.


  1. AB+BC+CA = 2 AM

  2. AB+BC+CA > 2AM


Solution

The correct option is B

AB+BC+CA > 2AM


Sum of all the angles in a triangle is 180.
The third angle in the given triangle is 180 - (60 + 70) = 50
All the angles in the triangle are different.
Therefore, it is not an isosceles triangle.
