A scalene triangle is one that has three lengths of different sizes. It is quite possible for a right triangle to have three sides of different length.
False.
True because it complies with Pythagoras' theorem.
Sometimes. "Scalene" simply means that the three sides have different lengths. This does not imply that the triangle has to have an obtuse angle.
In a triangle, if all of the angles are 60 degrees, then all three sides of the triangle are equal to each other. Basically, if the angles are equal than the sides must be equal. This kind of triangle is called an equilateral triangle.
