Geometry Honors Study Guide
7 units with lessons, worked examples, graphs, and practice PDFs.
Units
Logic, Axioms, and Proof
What counts as an argument. Geometry is the course where students first have to justify rather than compute, and this unit sets that expectation.
3 lessons · Problems and solutions PDFs →
Lines, Angles, and Constructions
Angle relationships that generate equations, and compass constructions that rely on equal radii rather than measurement.
3 lessons · Problems and solutions PDFs →
Triangles, Congruence, and Similarity
When two triangles are the same, and when they are the same shape at a different scale. The criteria are the unit, and knowing which do not work matters as much as which do.

Polygons and Quadrilaterals
Angle sums and the family tree of quadrilaterals, where each special case adds one property to the one above it.
3 lessons · Problems and solutions PDFs →
Circles and Conic Sections
Circle relationships and the wider family of curves that come from slicing a cone. Completing the square is the recurring technique.
3 lessons · Problems and solutions PDFs →
Transformations and Coordinate Geometry
Moving figures without changing them, and the one transformation that does change size. Order matters, which is the main source of error.
3 lessons · Problems and solutions PDFs →
Solid Geometry and Geometric Systems
Three-dimensional measurement and a look at how geometry itself is built from axioms. Composite solids are decomposed into parts whose measures add.
