Help me find weather or not these sides satisfy the triangle
schepotkina [342]

Answer:

No, the sides do not satisfy the triangle.

Step-by-step explanation:

OK, so you can use either use the Pythagorean Theorem or the 45-45-90 Triangle Theorem to find the answer to the question. I am going to use both in this explanation to help you see how they can be used.

Pythagorean Theorem:

a^{2}+b^{2}=c^{2}

45-45-90 Triangle Theorem:

a = b and c=a\sqrt{2} or b\sqrt{2}

Use Pythagorean Theorem:

So a=2\sqrt{3}, b=2\sqrt{3}, and c=6.

(2\sqrt{3})^{2}+(2\sqrt{3})^{2}=6^{2} ?

(4×3) + (4×3) = 36 ?

12 + 12 ≠ 36

24 ≠ 36

Sides do not satisfy the triangle.

Use 45-45-90 Triangle Theorem:

6=2\sqrt{3} \sqrt{2} ?

6=2\sqrt{6} ? no

Sides do not satisfy the triangle.
