The side opposite the 30° angle is shortest, the side opposite the 60° angle is in the middle (length wíse) and the hypotenuse is the longest. The shortest side is half the length of the hypotenuse.
False.
Does 742 = 242 + 702? If so, it is a right-angled triangle; if not, it isn't...
There's an infinite list of 3-number sets that can be the lengths of the sides of aright triangle. The only fact that's true of all of them is:(square of the length of the longest side) = (sum of the squares of the lengths of the other two sides.)
A right angle triangle can be scalene. Such a triangle has one right angle, two other unequal angles and no equal sides
Sometimes. "Scalene" simply means that the three sides have different lengths. This does not imply that the triangle has to have an obtuse angle.

True because it complies with Pythagoras' theorem.

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 In order for this to be a right triangle, the sum of the squares of the two shorter sides would have to equal the square of the longest side. 102=100 242= 576 272=729 102+242= 676, which does not equal 272=729, so a triangle with these lengths is not a right triangle.
For a triangle to exist, the sum of the shorter two sides must be longer than the third side.
