# Basic Geometrical Ideas

Aren’t video games just amazing? They’re so much fun to play, they seem so real especially because of depth, and movement in them. But how is this created? What helps videos games in helping viewers like you experience depth and movement? Well, the simple answer to this is ‘geometry’. These games use geometry to help viewers experience depth and movement. Geometry allows us in determining how the shapes and figures fit together to maximize efficiency and visual appeal. So, let us get acquainted with geometry basics ideas.
