Yes, it is.
Does 742 = 242 + 702? If so, it is a right-angled triangle; if not, it isn't...
No. But they can be the lengths of the three sides.
It would be an isosceles right triangle. The two sides that aren't the hypotenuse are equal, with lengths of 16.971 (rounded) .
A triangle is right triangle if square of the longest side is equal to sum of squares of other two sides. Square of 24 = 576 Sum of square of 9 and 21 = 92 + 212 = 81 + 441 = 522 576 ≠522. It is clear that triangle is not a right triangle.
Yes, these measurements work for a right triangle. 7^2 + 24^2 = 25^2 Good luck. :-)
No because it does not comply with Pythagoras; theorem if the lengths were 10, 24 and 26 then it would be.

Yes because they comply with Pythagoras' theorem for a right angle triangle
True because it complies with Pythagoras' theorem.
8cm !
No. But they can be the lengths of the three sides.
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.

YES. 18 and 24 are the two leg lengths and 30 is the hypotenuse then by Pythagoras' Theorem :- 182 + 242 = 302 324 + 576 = 900......which is true and therefore the three side lengths 18, 24 and 30 do form the sides of a right-angled triangle.
24cm each
If it is then 742 would equal 702 + 242. 742 = 5476; 702 = 4900, 242 = 576. Pythagoras is satisfied so your triangle is indeed right-angled.
A triangle can't have sides with lengths of 12, 12, and 24. Well, maybe you might call it a 'degenerate' triangle', with angles of 0°, 0°, and 180°. The two sides of 12 and 12 together are just exactly long enough to reach from one end of the 24 to the other, so they flop down and lie right on top of it. When you look at this 'triangle', it looks like a single line with a length of 24.
