Add the squares of the two smaller sides. Is it equal to the square of the biggest side? If yes, it is a right angled triangle.
82 + 152 = 64 + 225 = 289
172 = 289
The same, so it is right angled.
Yes.

False. It can't be.In a right triangle, the sum of the squares of the two short sides is equal to the squareof the longest side.122 = 144152 = 225-------------sum = 369202 = 400, not 369.So these are not the sides of a right triangle.
a scalene triangle is a triangle with three differant sides
do you have an angle measure? (if it is an equilateral triangle all legs will be 8 but i don't think this applies in your case)
Yes.
A scalene triangle
Yes.
yes
Yes they do. We find this by applying the pythagorean theorum. Since 9^2 + 12^2 = 15^2, they form a right triangle.
The lengths of the legs of a right triangle are 15 cm and 20 cm. What is the length of the hypotenuse?
No
No.
What is the 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.
The length of the hypotenuse of a right triangle with legs of lengths 5 and 12 units is: 13The length of a hypotenuse of a right triangle with legs with lengths of 5 and 12 is: 13
