Question

each angle is greater than 60 degree ?

each angle is lesa than 60 degree?

each angle is equal to 60 degree?​

Answer 1

Step-by-step explanation:

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°. ... 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°

Answer 2

Answer:

1= (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. 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°.

2= No, a triangle cannot have all angles less than 60°, because if all angles will be less than 60°, then their sum will not be equal to 180°. Hence, it will not be a triangle.

3= In a triangle if each angle is equal to 60° then it is an equilateral triangle.
