Answer:
1, no 2, yes 3, yes 4, yes
Step-by-step explanation:
Using the Pythagorean theorem([tex]a^{2}[/tex]+[tex]b^{2}[/tex]=[tex]c^{2}[/tex])
1. [tex]6^{2}[/tex]+[tex]8^{2}[/tex] [tex]\neq[/tex] [tex]9^{2}[/tex] ( 36+64 [tex]\neq[/tex] 81 )
2. [tex]5^{2} + 12^{2} = 13^{2}[/tex] ( 25+144=169 )
3. [tex]6^{2} + 8^{2} = 10^{2}[/tex] ( 36+64=100 )
4. [tex]3^{2} + 4^{2} = 5^{2}[/tex] ( 9+16=25 )
