Chapter Overview
This chapter focuses on locating points on the Cartesian plane using coordinates. It introduces formulas for calculating the distance between two points, the coordinates of the midpoint, and the area of a triangle formed by three points. These concepts are essential for understanding the geometry of shapes and figures using algebraic methods.
Important Keywords
