Examples For Geometry Daily

What This Resource Actually Looks Like in Practice

Examples For Geometry Daily is a collection of step-by-step geometry problems posted on a regular schedule, meant for students and teachers who want consistent practice material. The format is straightforward: a problem statement, often with a diagram, followed by a worked solution that walks through the logic rather than just presenting the final answer. It targets high school level geometry but the problem set extends into early competition math territory depending on which day you pull from. I found this resource about three years ago when a student of mine was stuck on circle theorems and needed something more than textbook exercises. The daily posting cadence meant there was always fresh material, and the worked solutions showed the reasoning path, not just the answer. That distinction matters more than people admit. Most geometry practice sources give you a problem and a final number. Examples For Geometry Daily gives you the chain of reasoning — which angle bisector property applies, why a particular auxiliary line makes sense, how the similar triangles were spotted. Here is how I use it in a real classroom setting. I assign one problem per day as a warm-up. Students work it for about eight minutes, then we go over the solution together. The whole thing takes roughly twelve minutes before the rest of the lesson begins. That is fast enough to maintain momentum and structured enough that students actually engage with the material rather than flipping ahead to see if the answer looks familiar.

The site itself is simple. You do not need an account to access the problems, which is unusual these days and worth noting. You just navigate to the daily post, view the problem, and scroll down for the solution. There is a search function that lets you filter by topic — triangles, circles, coordinate geometry, transformations. The archive goes back quite far, so if you need a specific type of problem on a certain difficulty tier, you can pull it up even if it was posted months earlier. One edge case that came up for me: the diagrams are not always to scale, and a few problems rely on you noticing that an angle looks like it might be a right angle when it is not. I ran into this with a problem involving cyclic quadrilaterals where the visual layout suggested perpendicular diagonals, but the correct approach required using the inscribed angle theorem instead. I had to tell my students explicitly to treat every diagram as schematic unless the problem states otherwise. That is one of those things that does not get mentioned in most geometry guides but will cost points on an exam if you ignore it. Another practical detail: the solutions sometimes skip a step or two, assuming you can fill in the gap. It is written at a level where the author expects you to already know basic properties like the triangle sum theorem or the Pythagorean theorem. If you are working through this solo without a textbook nearby, you will find yourself pausing more often than you should. The workaround is to keep a reference sheet of common geometry theorems open while you work. I use a printed sheet with the standard results — angle relationships, similarity criteria, circle theorems, area and perimeter formulas. It cuts the time spent looking things up from about five minutes per problem to under a minute.

The difficulty curve is not perfectly linear. Some days you get an straightforward coordinate geometry proof. The next day you might get a problem that requires constructing an auxiliary line in a non-obvious way, which is the kind of thing that separates students who memorize theorems from students who actually do geometry. The site does not label difficulty levels explicitly, which I find both a strength and a weakness. You have to judge it yourself as you go through the archive. If you are looking to download or save problems for offline use, there is no bulk export feature. You can print individual pages or screenshot them, but there is no single file or PDF compilation available. I worked around this by running a simple browser extension that batch-saved the last sixty days of posts into a folder on my drive. It took about twenty minutes and gave me a year's worth of practice problems organized by date. If you need this for a semester-long course, that effort saves you from clicking through each day individually. There are limitations worth being honest about. The resource focuses heavily on Euclidean plane geometry. If you need solid geometry — three-dimensional figures, vector-based proofs, or analytic geometry in higher dimensions — you will not find it here. The trigonometry coverage is also thin. You get occasional problems that use sine and cosine rules, but there is no dedicated section for that. For a student building a complete geometry skill set, this should supplement other materials, not replace them.

Another bottleneck: the problem topics rotate somewhat unpredictably. You might get three triangle problems in a row and then jump to polygons with no transition. If you are using this for targeted practice — say, you know you need more work on triangle similarity — you will spend time filtering through the archive to find the right problems rather than getting a focused set. The search function helps, but it is not granular enough to pull only similar triangle problems from a specific date range. The content is accurate. I have not encountered any errors in the solutions, which is more than I can say about half the free geometry resources online. The explanations are clear but not hand-holdy. That means it works well for someone who already has a baseline understanding and needs practice applying it, but it will frustrate a complete beginner who has never seen a proof before. For classroom use, the daily posting schedule is genuinely useful. I have seen students who skip homework consistently show up prepared when there is a daily problem with a fixed time slot. The accountability of a set schedule changes behavior more than any assigned workbook page ever did. I run it as part of the first twelve minutes of class, grade it informally, and track progress over a nine-week period. The improvement in proof-writing quality is measurable, though the gains taper off after about six weeks unless you introduce harder problems from the archive manually.

Access is free. The main page is at the Examples For Geometry Daily website, and the problems are posted as individual pages with persistent URLs. Bookmarking the current day's problem is the most reliable way to keep up without searching each time. The archive URL pattern is predictable, which means you can navigate to any past date if you know the URL structure. Overall, it is a solid, no-frills resource that does one thing well and does not try to be everything. If your goal is steady daily practice in plane geometry with full worked solutions, it fits that purpose without excess. If you need something broader or more structured, you will need to layer in additional materials to fill the gaps.
