Muscles cannot push, they can only pull which means they work in pairs in order to move, this is known as antagonistic pairs. For example with a bicep curl you have the agonist/ prime mover (Bicep) and the antagonist/ Opposing muscle group (Triceps). As the agonist contracts it pulls the antagonist which relaxes.
there are upto four functional groups of muscles acting on joints. 1 agonist: actively contract to make a movement. muscle length reduces. 2. antagonist: resists the muscle on opposite side, thereby controls the speed of the agonist muscle contraction. that's why they say both agonist and antagonist muscles are working in pairs. furthermore when the movement is reversed the original agonist becomes the antagonist and the original antogonist becomes the agonist. hence antagonist pairs. right? 3. stabilisers: some muscles will hold the joint area stable while other three types of muscles are making a movement. 4. modifiers: some muscles can slightly change the direction of force exerted by agonists dynamically.

which two pairs of muscles are antagonistic pairs?
One is the agonist and the other is called the antagonist. Agonist: muscle which is the main mover, it contracts and shortens Antagonist: muscle that lengthens and controls e.g. flexion at the elbow: the biceps are the agonist and the triceps are the antagonist.
Antagonistic pair is a combination of agonist and antagonist muscles that only one contracts and the other one relaxes. The biceps in a human body are an example of it.
Perhaps you mean antagonist and agonist muscles often occur in pairs, called antagonistic pairs. As one muscle contracts, the other relaxes. An example of an antagonisic pair is the biceps and triceps; to contract - the triceps relaxes while the biceps contracts to lift the arm.
The antagonist to the gastroc and soleus muscles is a combination of muscles, primarily the tibialis anterior and fibularis (peroneus) tertius.
