Not true. An obtuse or right angled triangles can be isosceles.
It depends on the sizes of the two smaller angles. An isosceles
triangle has two equal angles so a triangle with angles of size [A,
(180-A)/2, (180-A)/2] degrees where 90 < A < 180 degrees
would be an obtuse angled isosceles triangle. A triangle with
angles of size (90, 45, 45) degrees is a right angled isosceles
triangle.
