Step-by-step explanation:
Pythagorean theorem
![a^{2} +b^{2} =c^{2}](https://tex.z-dn.net/?f=a%5E%7B2%7D%20%2Bb%5E%7B2%7D%20%3Dc%5E%7B2%7D)
![6^{2}+ 9^{2}\\ =117\\\neq 12^{2}](https://tex.z-dn.net/?f=6%5E%7B2%7D%2B%209%5E%7B2%7D%5C%5C%20%3D117%5C%5C%5Cneq%2012%5E%7B2%7D)
![7^{2}+ 10^{2}\\ =149\\\neq 12^{2}](https://tex.z-dn.net/?f=7%5E%7B2%7D%2B%2010%5E%7B2%7D%5C%5C%20%3D149%5C%5C%5Cneq%2012%5E%7B2%7D)
![16^{2}+ 18^{2}\\ =580\\\neq 25^{2}](https://tex.z-dn.net/?f=16%5E%7B2%7D%2B%2018%5E%7B2%7D%5C%5C%20%3D580%5C%5C%5Cneq%2025%5E%7B2%7D)
![27^{2}+ 36^{2}\\ =2025\\= 45^{2}](https://tex.z-dn.net/?f=27%5E%7B2%7D%2B%2036%5E%7B2%7D%5C%5C%20%3D2025%5C%5C%3D%2045%5E%7B2%7D)
