anonymous · Answer

$$\sqrt{41}$$, 4,5

anonymous · Answer

pythagorean theorem
$$A^2+B^2=C^2$$

if the numbers dont fit into that, then its not a right triangle

remember C is the hypothenuse (longest side)

anonymous · Answer

And the sides $$2\sqrt{26}$$ 15 and 11

anonymous · Answer

the first is a right triangle 41=41?

anonymous · Answer

$$2*\sqrt{26}=\sqrt{4}*\sqrt{26}=\sqrt{4*26}$$

anonymous · Answer

have more confidence in your own abilities, and i dont have a calculator infront of me

16+25=41 so i assume so

anonymous · Answer

yes its 41=41, and the second one I got 121+225=10.1 so not a right triangle

anonymous · Answer

you might want to recalculate C

$$\sqrt{4*26}=\sqrt{104}$$

$$\sqrt{104}^2=\pm104$$

but yes it is not a right triangle

oh okay, thank you
