The length of the third side of the triangle is 4.5 units.
What is Pythagoras Theorem?
The Pythagorean theorem, or Pythagoras' theorem, is a fundamental relation in Euclidean geometry among the three sides of a right triangle.
Here, sides of triangle is AB = 4 , BC = 2
By Pythagoras Theorem,
AC² = AB² + BC²
AC² = 4² + 2²
AC² = 20
AC = √20
AC = 4.47
AC = 4.5
Thus, the length of the third side of the triangle is 4.5 units.
