A.True

3. marcoduuuh Group Title

Thaaaaankss! :D

4. LukeBlueFive Group Title

False, since the square of the hypotenuse is not equal to the sum of the squares of the other two sides. From the Pythagorean Theorem: $34 ≠ 18 + 18 = 36$

5. iAmCool Group Title

Mhm.. welcome:D

6. marcoduuuh Group Title

Wait, false or true then?

7. iAmCool Group Title

True, because it has a right angle. Like a 'L' shape.. It has 18 and 18 angles

8. LukeBlueFive Group Title

The Pythagorean Theorem states that the square of the hypotenuse is equal to the sum of the squares of the other two sides. Since this is not the case with this triangle, it must not be a right triangle, since the theorem holds for all right triangles.

9. iAmCool Group Title

Wait? Yes it is.. o.o

10. iAmCool Group Title

It is a right triangle! o.o

11. iAmCool Group Title

Oh wait.. :3 NO it's not. :) Your are correct, my bad..

12. marcoduuuh Group Title

Aaaaaah. Yep, t'was false. Thanks guys! (:

13. iAmCool Group Title

Yeah. I just scanned the photo and saw the right angle not a right triangle. :P

14. LukeBlueFive Group Title

Taking the Pythagorean Theorem: $hypoenuse^2 = 2 \times sides^2$ And our specific example: $2 \times \sqrt{18}^2 = 2 \times 18 = 36$ This is not equal to $\sqrt{34}^2 = 34$ Therefore, this is not a right triangle, it just greatly resembles one.
