Description

Coordinate Geometry: Proof and Measurement on the Plane is Unit 4 of Geometry: Structure, Proof, and Measurement (Grade 10), the Letters & Devotion Math course, complete in one printable PDF: 10 lessons, the unit check-up and the answer key, 82 pages.

• The distance formula as a Pythagorean-theorem application
• Slope criteria for parallel and perpendicular lines
• Midpoint formula and ratio-based segment partition
• The logical link between slope/distance evidence and the definition of a parallelogram
• Coordinate proof of rectangle/rhombus properties
• Strategic placement of a figure on coordinate axes
• Original coordinate proof construction from a verbal description
• The gap between visual appearance on a grid and a computed coordinate proof
• The relationship between synthetic proof and coordinate proof of the same geometric fact
• Distance formula, midpoint formula, slope criteria for parallel/perpendicular

Every lesson is written for a parent with no teaching background: it opens with a short script to read aloud, names the specific wrong idea a student is likely to reach for and how to correct it, and closes with a practice sheet you may copy for your household. Scripture references are King James Version throughout. Black-and-white, 8.5 x 11 in. The whole year of this course is also in this store as a single book.
