Yes.

3, 5, 5 does not make a right angle triangle but they can make an isosceles triangle Correct. Try 3,4,5. That will be a right triangle. 3x3 plus 4x4 = 5x5
No. If 0.3 and 0.4 are the legs of a right triangle, then the third side has to be 0.5 .
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.
No because the dimensions given do not comply with Pythagoras' theorem for a right angle triangle
Any shape that is enclosed and has three sides is a 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.
it should make a triangle I dont know about a right triangle because in order for three sides to make a triangle the sum of the two smallest sides need to be bigger than the biggest side in this case the sum of the two smallest numbers is 34 and the biggest side is only 26 making the two smaller sides bigger than the biggest side ------ Yes, they make a right triangle if 10(a) and 24(b) are the legs and 26(c) is the hypotenuse because of a^2+b^2=c^2.
