The two equal angles of an isosceles triangle can be any number of degrees between (but not including) 0 and 90 degrees, say y degrees. The third angle would then be (180 - 2y) degrees.

101 degrees :p
In an isosceles right angled triangle,1 angle is 90 degrees and the other two are equal ,each is 45 degrees
An obtuse triangle or a right angle triangle. An equilateral is definitely an isoceles triangle * * * * * 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.
No, an isosceles triangle can not be a right triangle, because a right triangle has an angle of 90 degrees angle, and two angles of 45 degrees. An isosceles triangle has all acute angles, therefor, making it an acute triangle, so no, an isosceles triangle is not, i repeat not, a right triangle.
a right angled triangle with the remaining angles both being 45 degrees will be a rightangled triangle and an isosceles triangle.
