Question

Q11) Give reason
(a) A triangle cannot have each angle
equal to 60°

(b) A triangle can have each angle
equal to 60

(C.) A triangle cannot have cach !
angle less than 60°
​

Answer 1

Step-by-step explanation:

Reasons

(a) Sum of all angles of triangle is 180°, if all angles of the triangle are greater than 60° their sum will be more than 180°.Thus it will not be able to form triangle with such angles.

(b)60°+60°60°=180°

So a triangle can have each angle equal to 60°.

(c)If the all angles are less than 60° their sum will also be lesser than 180°.That's why triangle cannot have each angle less than 60°.
