Correct Answer
Option D
Explanation
To determine which set of sides can form a right-angled triangle, we use the Pythagorean theorem. According to this theorem, in a right-angled 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 lengths of the other two sides. Mathematically, this is expressed as: \[ c^2 = a^2 + b^2 \] where \( c \)тАжRead More
