Question

73. How many diagonals does a convex polygon with n sides
have? (Recall that a polygon is convex if every line seg-
ment connecting two points in the interior or boundary of
the polygon lies entirely within this set and that a diago-
nal of a polygon is a line segment connecting two vertices
that are not adjacent.)​

Answer 1

Answer:

nc2-n

Step-by-step explanation:

select any two points in the diagnosis such that a diagonal forms but if you take adjacent sides it is a side so such selections are nc2-n
