Question

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

Answer 1

No

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
