![]() Select a point you have plotted and click on the coordinate constraint tool to force the point to be at a particular location on the coordinate plane. □You can graph a polygon on the coordinate plane, too. □ Force an angle to be exactly 63 degrees by selecting the two rays or segments that make the angle, then selecting the angle constraint tool. □ Force two segments to be congruent by selecting the segments, then selecting the congruent constraint tool. □ Force a right angle by selecting the intersecting lines or segments, then click on the right angle constraint tool. □ Force two lines or segments to be parallel by using the parallel constraint tool PowerPoint is not as powerful as Math Illustrations or Geometer's Sketchpad or Geogebra (I don't have as much experience with Geogebra). What's great about the heptagon above is that if you click and drag on one of the vertices, all sides change accordingly since it's a regular polygon.Īt the time of writing, I don't teach Geometry and haven't done for about 5 years, but I still use Math Illustrations on occasion to make a diagram for my Precalculus or Calculus class. I made this regular heptagon in less than 5 seconds.Īny of the annotations/text that you don't want can be easily hidden. ![]() The toolbars where all of the magic happens. With Math Illustrations there's a button on one of the toolbars that quickly allows you to create a regular n-gon in less than 5 seconds! In one of my undergraduate classes in the late 90s, we spent a lot of time learning how to construct parallel lines or regular polygons using Geometer's Sketchpad.īut if I wanted a regular hexagon to put on a worksheet, I didn't have time to construct one (or research how to do it since I had forgotten).
