# Coordinate Geometry

## Definition

The Distance between two points.

## Different Quadrants Each Quadrant has different signs. Such as Positive or Negative. In Quadrant 1 , It has a Positive Y and Positive X Axis. In Quadrant 2 , it has a Positive Y and Negative X Axis. In Quadrant 3 , it has Negative Y and Negative X . And In Quadrant 4 , It has A Negative Y and Positive X Axis. | | If the letter is on the same side , and are the same they could be congruent angles or even congruent sides. BC could be equal to AC. or even be Greater than BC. |
