An isosceles triangle is any triangle with at least two sides of equal length. Logically, an isosceles triangle also has at least two angles of equal size. An equilateral triangle is a triangle with three equal sides and three equal angles (all of which are 60 degrees). Since it has at least two equal sides then it is therefore also an isosceles triangle. This is no different to the way in which a square is also a rectangle, or a circle is also an ellipse. They are simply special cases of the general case.
An isosceles triangle has three equal angles, each of 60 degrees. ------------------------------------------------------------------------------------ An isosceles triangle has two sides of the same length and therefore two equal angles. It does not need to have three equal sides/angles to be isosceles.

If a triangle is obtuse then is it isosceles?
An obtuse triangle is not necessarily isosceles, but it can be.
Is a right triangle always an isosceles triangle?
No. An isosceles right triangle is a special case. There are many right triangles which are not isosceles.

How do you draw an isosceles scalene triangle?
You cannot. An isosceles triangle cannot be scalene and a scalene triangle cannot be isosceles. So an isosceles scalene triangle cannot exist.
