3C - Content video: The distance between two points
This video covers the theory and an example relating to the distance between two points.

|
■ The distance between two points, \(A(x_1 , y_1)\) and \(B(x_2 , y_2)\), is given by \[distance=AB=\sqrt{(x_2-x_1)^2+(y_2-y_1)^2}\] |
3C - Example 1: Applying the distance formula
Consider the points \(A(4,5)\) and \(B(2, a)\). Determine the value(s) of \(a\) such that the distance, \(AB\), is \(\sqrt{5}\) units.
