Step-by-step explanation:
The three main principles of the Virginia Plan were proportional representation, bicameral legislature, and the selection of the executive and judiciary branches by the legislature.
Proportional representation means that the number of representatives in both houses of the legislature would be determined based on the population of the state. This gave more political power to the more populous states, such as Virginia.
The Virginia Plan also called for a bicameral or two-house legislature, with the lower house elected by the people and the upper house elected by the lower house. The executive and judicial branches would be chosen by both houses of the legislature.
