Step 1: Locate the coordinates of the endpoints.

            EXAMPLE: The two endpoints M (2, 1) and N (6, 4). Therefore,

             (x_1, y_1) = (2, 1) and (x_2, y_2) = (6, 4).

Step 2: Find the length of AC and AB

           Step 1: Locate the coordinates of the endpoints.

            EXAMPLE: The two endpoints M (2, 1) and N (6, 4). Therefore, (x_1, y_1) =

           (2, 1) and (x_2, y_2) = (6, 4).

          Step 2: Plug the corresponding coordinates into the Distance Formula. .

          FORMULA:

          d = \sqrt{(x_2 - x_2)^2 + (y_2 -y_1)^2}

          EXAMPLE: Endpoints M (2, 1) and N (6, 4).

          d = \sqrt{(6 - 2)^2 + (4 - 1)^2}

         Step 3: Calculate the subtraction in parentheses.

         Step 4: Square the value in parentheses.

         Step 5: Add the numbers under the radical sign.

Step 3: Substitute the either lengths in the given condition

          EXAMPLE: A (7, 4) and B (2, 0), The point C has coordinates (2, t), to find t

          We can find the t value by this condition AC = AB

Step 4: Simplify the equation to find the unknown variable

            NOTE: Apply the BODMAS rules
