Step-by-step explanation:
45°, 45°, 90° triangle theorem states that:
Lengths of the sides opposite to the 45° angle are equal to one upon root two times of the length of hypotenuse.
Mathematically it can be expressed as:
[tex]length \: of \: sides \: opposite \: to \: 45 \degree \: \\ angle \\ = \frac{1}{ \sqrt{2} } \times length \: of \: hypotenuse.[/tex]
