The program shows some of the polygons' properties. Student can build his or her own figure and check its properties. He can compare the length of segments, measure the angles and illustrate the periphery and area.
Being precise - to draw a polygon you have to define consecutive points which build the figure. Next you can analyse the properties of the polygon. Particularly you can add a free point on the pane or a point attached to a segment either a point dividing the segment into half or any point of segment. For each point you can find its project on a segment. In triangle this allows constructing heights and medians.
With this application you can compare segments on three levels - it can be dependent of side's length or diagonal's length or polygon's periphery. Similarly you can compare angles on three groups, both analyse sum of angles or compare measures between angles.
After choosing the "area" option you can find out how the area changes when you resize the figure. How some measurements affect the area.
There are some questions for students with possibility of evaluation and expanding and prepared worksheets.
