10. Sorry Try Again Back

11. a 2 + b 2 = c 2 C=√A+√b a=√c-√b b=√c-√a Next Back

12. a 2 + b 2 = c 2 ??? 6 cm 8 cm Next Back 6 2 + 8 2 =c 2 36+64=c 2 100 = c 2 √100=c 2 C=10

13. 3 cm 4 cm ??? Next Back

14. a 2 + b 2 = c 2 8 cm ??? 2 cm Next Back A = √c 2 - √b 2 A = √8 2 - √2 2 A = √46 - √4 A = √60 A =7.7

15. 5 cm ??? 8 cm Next Back

16. Pythagorean theorem a 2 + b 2 = c 2 Next Back hypotenuse 9090
