No.
If the cross-product are equal the ratios are equal. Thus, a/b = c/d if (and only if) ad = bc
Each pair of opposite sides has equal slopes.
It has two pairs of angles. Each pair of opposite angles is equal.
A kite, a square or a rhombus
Yes, each pair of two opposite sides is parallel and equal in length. This is necessary to achieve the symmetry of the angles.
If the cross-product are equal the ratios are equal. Thus, a/b = c/d if (and only if) ad = bc
Any pair of numbers of the form 52*k : k where k is an integer.
The answer will depend on what the ratios are. But since you have not bothered to provide that information, I cannot provide a sensible answer.
no
Not necessarily.
They are convex polygons. They have four sides. They have four vertices. Each pair of opposite sides is equal. Each pair of opposite angles is equal.
1000/2 is one possible pair.
Each pair of opposite sides has equal slopes.
how the force in each force pair related
you have to times and get the answer correct or not
There is no equation, let alone a pair of them!
In magnitude.
