than it's all angles are equal 60' and it is a isosceles triangle
kamla5:
this is a question of linear equation
just two angles are equal
sorry
because of confusion
let me explain
all angles need but be 60 in isosceles triangles
it may be 20,20,140
* need not be
sorry friends
it's my mistake

if two angles are equal in a triangle, we can say that it is an isosceles triangle.
let the equal angle be x,
let the other angle be y.
then linear equation will be:
180=x+x+y
180=2x+y
let the equal angle be x,
let the other angle be y.
then linear equation will be:
180=x+x+y
180=2x+y
thinks
thanks
you are welcome
