There are 5 sets of 3 parallel diagonals (where one is a major diagonal and 2 of them span 2 vertices. Each set makes 3 pairs, so there are 5 * 3 = 15 pairs.
There are 5 sets of 4 parallel diagonals (where 2 of them span 1 vertex, and 2 of them span 3 vertices. Each set makes 6 pairs, so there are 5 * 6 = 30 pairs.
So that's 15 + 30 = 45 pairs.

how many diagonals decagon have?
35
How many parallel sides does a decagon have?
A decagon can have 0, 2, 3, 4, 5, 6, 7, 8, 9 or 10parallel sides, depending on its layout.A decagon has 10 sides. Any regular polygon with four or more sides and even vertices will have pairs of sides that are parallel. A regular decagon will have 5 pairs of parallel sides.It is possible for a decagon to have 2 groups of 5 parallel sides. (For example, a block letter F).
