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).

Coordinate_plane_proofs

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

Dividing_line_segments

Think about ratios of lengths of segments between points.

Equations_of_parallel_perpendicular_lines

Learn all about equations of parallel and perpendicular

Distance_and_midpoints

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