Use the Distance Forumla to find the lengths of the diagonals of a polygon with vertices A(0.3), B(3,3), C(4,1), D(0,-1), and E(-2,1). Please explain this =)
2. A pentagon has 5 diagonals. The length of two of the 5 diagonals is obvious:
|AD| = 4 and |CE| = 6
3. The distance between the points and is calculated by:
4. The length of AC:
5. The last two diagonals are calculated in just the same way. Good luck!
