Lines of symmetry are indicated by a dotted line. A mirror can also be used to help find lines of symmetry. When a mirror is placed in a position on a shape, either vertically, horizontally or ...

Plotting a graph takes time. Often mathematicians just want to know the key features. These are: shape, location and some key points (such as where the graph crosses the axes or turning points).

Graph distinguishing numbers constitute a vital parameter in understanding the symmetry properties of graphs. Fundamentally, the distinguishing number of a graph is the minimal number of labels ...

Peg uses a magic ukulele to find the line of symmetry on shapes. Peg uses a magic ukulele to find the line of symmetry on shapes that form steps. The steps should lead her to the Kingdom of Day, where ...
