This SAT Sphere lesson focuses on essential SAT test topics in the Coordinate Geometry section. You'll build a strong understanding of core concepts, learn time-saving test-taking strategies, and apply your knowledge to realistic Digital SAT practice questions.
01
Introduction to Coordinate Geometry
Frames why plotting algebra on a Cartesian plane matters for the Digital SAT and reminds students to recall linear‐equation graphing, the Pythagorean theorem, and basic shape properties from previous lessons.
02
Plotting Points and Identifying Quadrants
Teaches how to place ordered pairs accurately on the plane and name their quadrants, building on earlier graphing experience from Functions and Their Graphs.
03
Slope and Line Equations
Introduces the slope formula and derives slope-intercept and point-slope forms, extending prior work with linear equations to a visual context.
04
Parallel and Perpendicular Lines
Shows how comparing slopes reveals parallelism or perpendicularity, refreshing angle-relationship reasoning from Basic Geometric Shapes.
05
Deriving and Using the Distance Formula
Develops the distance formula from the Pythagorean theorem and applies it to find lengths in the plane, refreshing right-triangle concepts.
06
Midpoint Formula and Segment Bisectors
Defines the midpoint as an average of coordinates and connects it to bisectors, building on previous averaging skills from Unit Conversion and Rates.
07
Partitioning a Segment in a Given Ratio
Generalizes the midpoint idea to any ratio, extending proportional-reasoning skills introduced in Ratios and Proportions.
08
Coordinate Proofs of Geometric Properties
Uses slope, distance, and midpoint tests to verify that figures are triangles, parallelograms, or rectangles, previewing concepts in Properties of Triangles.
09
Mixed Practice: Coordinate Skills
Provides SAT-style problems that integrate plotting, slope, distance, and midpoint calculations for cumulative mastery.
10
Key Takeaways and Targeted Practice
Summarizes core formulas, common SAT traps, and directs students to timed drills that spiral back to linear-equation graphing and right-triangle strategies.
