## anonymous one year ago Which triangle side lengths form a right triangle? Choose all that apply. 5, 6, 7 6, 8, 14 8, 15, 17 10, 12, 15 15, 20, 25 16, 18, 20

1. Nnesha

apply Pythagorean theorem $\huge\rm a^2 +b^2=c^2$ replace a b c by their values if both sides are equal then yes thse 3 numbers form a right triangle

2. Nnesha

remember : c is the longest side of right triangle so for first one c=7 plug in$\huge\rm 5^2 +6^2 =7^2$ both sides are equal ?

3. anonymous

no both sides arent equal right?

4. anonymous

so which one would be the best reponces? @Nnesha

5. Nnesha

$$\color{blue}{\text{Originally Posted by}}$$ @eugeniiaxo no both sides arent equal right? $$\color{blue}{\text{End of Quote}}$$ yes both sides are not equal so that's wrong

6. Nnesha

7. Nnesha

if you get equal sides then that would be your answer
