If a triangle is an obtuse triangle then it can not be an isosceles triangle.
True
False

Answer 1

I see that it's false...

Answer 2

We know that the sides opposite to two equal angles are equal

Answer 3

Suppose if two angles are equal, then two sides will be equal. This will tell that it is isosceles

Answer 4

False. the triangle may have 100 degrees for 1 angle, and the other 2 equal angles of value 40 degrees still it's an isosceles triangle.
