If you want to draw a regular polygon, select the second tool in the polygon menu. Move the points around and watch how the area changes. Notice how the area of the polygon appears in the algebra sidebar, along with the length of each Just choose the points you wish to join (or click to create new points), and when you're done, click back on the first point to close the polygon. Once you have had a go at drawing perpendicular lines, use the parallel line tool to draw some parallel lines in the same way.Дid you notice the other new tool? It's the polygon tool, and is useful for drawing sets of straight line segments that you want to form a polygon. Right-clicking and deselecting 'show object', or by toggling it in the algebra sidebar. GeoGebra constructs a line at right angles to your first one, passing through the point of your choice! By the way, if your diagram starts to get a little cluttered but you don't want to delete anything, you can always hide an object, by Choose the perpendicular line tool, then click on your line and your point (in either order). In the menu there are lots of other special lines you can construct for now, we will just concentrate on the first two, perpendicular and parallel lines.Дraw a line, and then draw any point, on or off the line. The first has the perpendicular line icon. Now we can draw points and lines, let's make it a little more interesting! The applet below has two new items in the toolbar. Lengths of different parts of your diagram! Notice that when you draw a line segment, its length appears in the algebra sidebar. A line segment just draws the section between the two points you choose, and a ray starts from one point, passes through the other point, and continues beyond.

Sometimes it's useful to draw a ray or a line segment rather than a full line. Once you've drawn the line, its equation appears in the algebra sidebar. Try clicking on two of your points with the line tool selected, and see the straight line between them appear. Once you've drawn a few points, you could try drawing some lines, using the third icon in the toolbar. A new point, labelled P, should appear at the coordinates (0,2). You can also add a new point using the input bar. If you change your mind about a point, you can delete it in several ways - select it with the move tool and press delete, or right-click on it in the graphics window or the algebra sidebar and select delete from the menu. GeoGebra will label your first point A, your second point B, and so on. If you then click on the move tool (the first icon, with an arrow), you can move your point around. The coordinates of your point appear in the algebra bar on the side. To draw a point, click on the second icon along (with the blue letter A) and then click on the page where you'd like the point to be.

There's a GeoGebra applet below for you to use to explore, if you haven't already downloaded the software for yourself. Let's start very simply, thinking about points and lines. I often use GeoGebra when I'm trying to understand a new geometry problem, and in this article I'd like to share some of the tools I find useful. GeoGebra also appears embedded in various problems on the NRICH site, so you may have already used it without even realising!
