Question 571966
i have a question that says "Given the lengths of the three sides, tell whether each of these are right triangles or not"
a)8,15,17
b)9,10,15
**
Remember the Pythagorean Theorem? 
The square root of the sum of the squares of the two legs(short sides)=hypotenuse(long side)
a) 8^2+15^2=289
√289=17
Therefore, these are dimensions of a right triangle
..
b) 9^2+10^2=181
√181≠15
Therefore, this is not a right triangle
