Question

I can't remember the process from when I did this back in High school, please iclude a step by step, thanks!

Answer 1

A sequence of 3 numbers like these can make a right triangle if the numbers $a,b,c$ form a Pythagorean triple.

When does this happen? $(a,b,c)$ is a Pythagorean triple if $a^2+b^2=c^2$, where $a,b$ are the 2 smaller of the 3 numbers.

Among these options, only (3, 4, 5) and (6, 8, 10) are Pythagorean triples.
