Question
Is the following statement true and false :
All the angles of a triangle can be greater than 60°.
Options
True
False
Solution
All the angles of a triangle can be greater than 60°
According to the angle sum property of the triangle
In ΔABC
∠A + ∠B + ∠C = 180°
Now, if all the three angles of a triangle is greater than 60°
Then,
∠A + ∠B + ∠C > 180°
