Question

a triangle has sides with lengths of 12kilometers,12kilometers,and 18kilometers. is it a right triangle?

Answer 1

Answer:

No

Step-by-step explanation:

$a^{2} +b^{2}=c^{2}$- Pythagorean Theorem

Let's substitute:

$12^{2} +12^{2}=18^{2}$

144+144=324

Does the above work?

No, so the triangle's sides do not form a right triangle
