5. The vertices of a parallelogram on a cartesian plane are as follows; (1,4), (2, 2), (6,3), and (5,5). Find the measure of the longest diagonal.​

first you need to understand what is a diagonal then if you understand them you can use the opposite coordinates to calculate the diagonals using the distance formula for example then after that you will subtitute the for x of opposite vertices same for y make sure if you get an answer you take a positive square root if i a root
