A series of free, online High School Geometry Lessons and solutions. Hexagon from One Side. ruler) and a pencil. By points, lines, and other basic tools, you can customize the graphics tool, to quickly build complex geometry, plus the function graph, to draw a wonderful world of geometry. An interactive online tool that allows dynamic creation and modification of ruler and compass constructions. Constructions may be built from one of five geometric primitives (Line, Line Segment, Ray, Circle, Perpendicular Bisector, and Intersection), and from other constructions; thus constructions may be built by composing more basic constructions. These constructions use only compass, straightedge (i.e. Using only a pencil, compass, and straightedge, students begin by drawing lines, bisecting angles, and reproducing segments. www.cs.rice.edu/~jwarren/grace/, Math Mammoth Geometry Worksheets Collection Robocompass uses a total of 22 drawing commands, such as draw a point, draw a perpendicular line, find an angle, reflect an object, and so on. Geometric constructions involve drawing geometric shapes that satisfy certain requirements using a straight-edge and a pair of compasses. Simple animations that show how to do basic geometric constructions. Philosophy of Constructions Constructions using compass and straightedge have a long history in Euclidean geometry. (Note: You can also see how to Use the Protractor, Use the Drafting Triangle and Ruler, and How to construct a Triangle With 3 Known Sides, but they are not "pure" geometric constructions. When they finish, students will have been introduced to 134 geometric terms and will be ready to tackle formal proofs. GRACE - Graphical Ruler and Compass Editor Pentagon. This is the "pure" form of geometric construction: no numbers involved!
