Coordinate Geometry
This chapter page turns the high-level subject view into an ordered learning slice, with direct links from curriculum items into topic and skill detail.
Ordered curriculum items
Each curriculum item can now route into topic and skill-level detail.
2
Plot ordered pairs
Use x- and y-coordinates to locate points accurately.
3
Read coordinates from a graph
Determine the ordered pair for a point in the plane.
4
Map a floor plan
Use coordinates to describe positions in a practical layout.
5
Compare locations
Use coordinate differences to describe left, right, up and down movement.
6
Find grid distances
Calculate distances when points share the same x-coordinate or y-coordinate.
7
Understand distance formula
Connect coordinate differences with the Pythagorean theorem.
8
Find distance between points
Compute distance in the coordinate plane using the distance formula.
9
Test collinearity by distances
Use segment lengths to determine whether three points lie on one straight line.
10
Find the midpoint
Average coordinates to locate the midpoint between two endpoints.
11
Find the missing endpoint
Use midpoint relationships to determine unknown coordinates.
12
Right triangle on a grid
Use squared distances to test the Pythagorean relationship.
13
Classify shapes by coordinates
Use side lengths and midpoints to identify geometric figures.
14
Verify with coordinates
Use an ordered procedure to test geometric properties on a coordinate plane.
