c² = 3² +4² = 9 +16
c = √25 = 5
The hypotenuse, c, will be 5.
_____
This "3-4-5" right triangle is the smallest set of integers that satisfies the Pythagorean theorem. The numbers form an arithmetic sequence. Any right triangle in which the sides are an arithmetic sequence will have the sides in this ratio -- 3:4:5. It is a useful "Pythagorean triple" to remember.
