In this dissertation, we start our study With rigidity theory that can test rigidity and flexibility of bar and joint frameworks in 2 dimension. different applications related to rigidity theory have been made in several fields. This theory has facilitated the development of the pebble game algorithms, and we implement a computer program to test the rigidity and flexibility of a given graph.
