How many pairs of perpendicular sides does this figure have?
The diagonals of a rectangle are never perpendicular but the diagonals of a square are perpendicular
There are 20 diagonals
Yes, the diagonals of a rhombus are perpendicular.
8 diagonals
4 diagonals
A square or other rhombus (= parallelogram with 4 equal sides, whether or not they're at right angles).Also, any other regular 4n-gon -- i.e., regular polygon whose number of sides is a multiple of 4 -- will have pairs of perpendicular diagonals. So a regular octagon has two such pairs.

It has 20 diagonals and is made up by 6 triangles

Yes 1 pair
You might be able to construct an irregular octagon that way, but for a regular one, no.
noNo, the diagonals of a rhombus are perpendicular to each other.Unless the rhombus is regular (and called a square) the diagonals are of different lengths.
A rhombic octagon. An ordinary regular octagon does have perpendicular sides. They do not meet in the outline of the octagon because they are alternate, but they are still perpendicular. However, in the same way that a rhombus is a distorted square, a rhombic octagon can have 4 pairs of parallel sides but no perpendicular ones.
An octagon has 16 diagonals.
