We also use these cookies to understand how customers use our services (for example, by measuring site visits) so we can make improvements. It is also worth noting that my opinion may be slightly biased as over 95% of all the geometry I have ever done was via hand-drawn diagrams.We use cookies and similar tools that are necessary to enable you to make purchases, to enhance your shopping experiences and to provide our services, as detailed in our Cookie Notice. TL DR: GeoGebra is fast and efficient, compass and straightedge gives you more time to internalize as you draw and reinforces intuition/relationships. The latter approach draws upon and reinforces my understanding of the deep connections between the circumcircle and the incircle, which is often useful for solving more complex problems. (Maybe I would have to do the extra step of making two auto-generated angle bisectors and intersecting them, but the point still stands.) If I was in an Olympiad setting and needed to draw an accurate diagram, I would start instead by drawing the circumcircle of the triangle, then drawing in the triangle itself, then drawing perpendiculars from the circumcenter to identify the midpoints of two of the three formed arcs, then connecting those points to the opposite vertices to make two angle bisectors, then drawing the incenter as the intersection of the angle bisectors. If I was on a drawing software, it's as simple as picking three points, connecting them, and finding an incenter button. Suppose the task was to draw a triangle and identify its incenter.
Geometry compass drawing how to#
I'm not quite sure how to put this into words but here's a little example that may shed some light. Draw an arc that crosses both sides of the angle, marking points on each line. Note: Teachers and Students from India can access/download Robocompass geometrical constructions and related materials from the following websites. On the other hand, I believe manually drawing these diagrams on paper with a compass and straightedge has contributed much more to my geometric intuition. Practice Compass and StraightEdge constructions. Large Circle Drawing Compass, line drawing, compass for geometry, Mandala compass, mandala circle, adjustable divider, artist compass 4 out of 5 stars (10) 60.71. Any decent stationers will have a wide range to choose from. It is of no use if a compass has all kinds of accessoires like extra lead fillers or a extra extension leg but fails to deliver consistency in drawing perfectly round circles. Everything beyond that basic feature is just a bonus. Not the magnetic kind, but the drawing kind. A great compass makes perfect circles A great compass is one that does what it promises. This allows one to empirically verify theorems that can then be mathematically proven. I prefer steel rulers, but as long as you avoid soft bendy rulers, you should be OK. It is also an invaluable tool for problem writing because you can change the setup of the configuration and watch all the other dependent points/lines/circles/etc. Put simply, I believe GeoGebra is great for quickly drawing diagrams and verifying conjectures. I have also used softwares like GeoGebra when training, and in my experience there are advantages and disadvantages to both systems.
I come from an Olympiad math background and thus have spent countless hours wielding my compass and straightedge to solve Olympiad geometry problems.
