Using Pythagoras theorem,
\(\displaystyle{8}^{{2}}={b}^{{2}}+{\left({4}\sqrt{{3}}\right)}^{{2}}\)
\(\displaystyle{b}^{{2}}={8}^{{2}}–{\left({4}\sqrt{{3}}\right)}^{{2}}=\)
\(\displaystyle={64}–{48}={16}\)
\(\displaystyle{b}^{{2}}={16}\)
\(\displaystyle{b}={4}\)

The converse of the Pythagorean theorem is also a true statement: If the sum of the squares of the lengths of two sides of a triangle is equal to the square of the length of the third side, then the triangle is a right triangle. Use the distance formula and the Pythagorean theorem to determine whether the set of points could be vertices of a right triangle.
