There are only three kinds of triangle - equilateral, where all three sides are the same - isoceles, where only two sides are the same - and scalene, where no sides are the same. The right triangle is a special case of the isoceles or scalene. Even if you consider the right triangle different, which is is not, that only make five kinds of triangle.
To determine if these three sides make a right triangle, we can use the Pythagorean theorem. In a right triangle, the square of the length of the hypotenuse (the side opposite the right angle) is equal to the sum of the squares of the other two sides. In this case, the squares of the two shorter sides are 3.6^2 = 12.96 and 1.5^2 = 2.25. Adding these together gives us 15.21. The square of the longest side, 3.9^2 = 15.21, which is the same as the sum of the squares of the other two sides. Therefore, these three sides do make a right triangle.
No, a right angled triangle needs an angle that is 90 degrees. Here, all the angles don't even make up 180 degrees.
For any right angle triangle its hypotenuse when squared must be equal to the sum of its squared sides in accordance with Pythagoras' theorem and so it appears that the given information would not make a right angle triangle.
