Getting Started with Geometry Ideas Weekly
It's a pattern-based approach to geometry learning that cycles through problem sets, visual proofs, and construction challenges on a weekly cadence. Most people treat it like a passive reading resource. That's the first mistake. It actually works when you actively redraw every figure from scratch before looking at any solution. I ran through the first cycle last fall when I was trying to rebuild my spatial reasoning skills after years of only doing coordinate-heavy work. The week-two problem set involves a configuration of three mutually tangent circles with a common external tangent line. Standard textbook fare. But the trick is that the problem never tells you which radius goes where upfront. You have to deduce it from the tangency conditions. I spent about forty minutes on that one before realizing I'd been assuming an ordering that wasn't stated. The workaround was to label the radii generically — a, b, c — and let the tangency equations force the correct assignment. Takes longer on paper but the insight sticks harder.
Why Geometry Ideas Weekly Works Differently Than Regular Problem Sets
Most geometry resources throw you at a problem and give you the theorem you need in the next paragraph. This approach deliberately withholds that scaffolding on purpose. The first time I hit that, I thought it was poorly edited. It's not. The delay between problem statement and guidance is intentional — it forces you to identify which configuration you're actually looking at before you start computing. That's the skill that falls apart first under test conditions anyway. The counter-intuitive part: the construction problems are more valuable than the proof problems. Everyone gravitates toward the theorem-heavy weeks because they feel more like "real math." But the weekly construction exercises — draw a figure satisfying these five constraints with only compass and straightedge — are where the actual geometric intuition gets built. I've seen people breeze through triangle similarity proofs and then freeze completely when asked to construct a specific tangent configuration from scratch. The construction weeks close that gap.
How to Actually Use It
Set aside the full weekly block before you look at anything. I know that sounds obvious but most people skim the problem statement, flip ahead to see what tools are available, and then come back to attempt it. Don't. Read the problem, close the page, and draw it from memory. Your first sketch will be wrong somewhere. That's the point. The correction process is where the learning happens. Use a fresh sheet for each attempt. I've been through enough eraser-smudged papers to know that redrawing over your own mistakes reinforces the wrong version. New sheet, new pencil, no looking back until you've committed to a configuration. Takes about twenty minutes per problem if you're doing it right. The whole weekly package usually runs about three hours total, not including the solution review. There's a specific edge case in the rotational symmetry weeks that trips almost everyone up. When the problem involves rotating a configuration around a point that isn't a vertex of any given figure, people tend to rotate around the origin or the nearest labeled point by habit. I made that mistake twice in a row during week eight. The workaround is to explicitly identify the rotation center before drawing anything. Write it down as a separate line: "Rotation about point P by 60 degrees clockwise." Forces you to commit to the right pivot before your hand starts moving. Once I started doing that, the success rate on those problems jumped significantly.

Where It Falls Short
It's not a comprehensive curriculum. The coverage is deliberately narrow — Euclidean plane geometry, mostly synthesis and construction. If you need analytic geometry, vector methods, or solid geometry practice, this won't give it to you. The weekly cadence also means you can't cram. The material builds cumulatively across weeks. Skipping a week creates a noticeable gap, especially around the inversion geometry section in month two. For people who need broader coverage, pairing it with a standard text like Coxeter's Introduction to Geometry or Kiselev's Geometry fills in the gaps without redundancy. The visual style complements rather than duplicates what those books cover. I found that working through the weekly problem alongside a parallel read-through of the relevant Coxeter chapters cut my confusion rate roughly in half compared to using either alone. The free materials are spread across a few community-hosted repositories and a mailing list archive. The official link is still a work in progress as of this writing, so searching for "Geometry Ideas Weekly" directly in your browser gets you the current access points faster than trying to navigate through secondary sites. The core weekly packets are freely available. The companion solution guides and extended problem sets require a subscription, which runs about what you'd expect for a niche educational resource. Whether it's worth the pay depends on whether you'll actually do the problems rather than just collect them.
