# Analytic geometry

In analytic geometry, also known as coordinate geometry, we think about geometric objects on the coordinate plane. For example, we can see that opposite sides of a parallelogram are parallel by by writing a linear equation for each side and seeing that the slopes are the same.

This course contains 6 segments:

**Distance and midpoints**

Find the distance between two points or the midpoint of two points.

**Dividing line segments**

Think about ratios of lengths of segments between points.

**Problem solving with distance on the coordinate plane**

Use what you know about distance to solve problems on the coordinate plan like finding the perimeter of a shape or determining if a point is on a circle.

**Parallel & perpendicular lines on the coordinate plane**

You probably know what parallel and perpendicular lines are. In this tutorial, you will learn how these relationships are expressed on the coordinate plane (spoiler: parallel lines have the same slope, and the product of the slopes of perpendicular lines is always -1).

**Equations of parallel & perpendicular lines**

Learn all about equations of parallel and perpendicular

**Coordinate plane proofs**

Prove properties of shapes by putting them on the coordinate plane and then using distances, midpoints, and slopes.
