Can a 6 8 10 make a right triangle?

yes

Step-by-step explanation:

using the converse of Pythagoras' identity.

If the square on the longest side is equal to the sum of the squares on the other two sides, then the triangle is right.

longest side = 10 , then 10² = 100

6² + 8² = 36 + 64 = 100

then 6, 8, 10 make a right triangle

answer: 45

step-by-step explanation:

no, her answer is not correct.   we square the lengths of all sides and then determine whether the pythagorean theorem holds here:

9² + 15² = 306.   this is not equal to the square of the longest side ( that square being 395.   answer c is correct.
