With this in mind, we continue our look into LibreOffice Draw by learning how to create polygons, arcs, and curves. A polygon is a plane object with at least three straight lines and angles. In geometric terms squares, rectangles, and triangles are types of polygons. For our purposes, we will discuss polygons with more than four sides. An arc, in Draw, is a partial circle or oval. You can make them filled or empty. A curve is a bent line. We will look at two methods for creating curves, the curve tool itself and the Bezier method.** | With this in mind, we continue our look into LibreOffice Draw by learning how to create polygons, arcs, and curves.

For quick access to the arcs and segments tools, we need to add the Circles and Ovals toolbar to the Drawing toolbar. Right-click the Drawing toolbar and select Customize Toolbar. This opens the Customize dialog. Click the Add button. Select Drawing under the Category list. In the Commands list, find the Ellipse tools – there are two. You want the one with the description “Using Customize toolbar, you can add the Ellipse icon which opens the Circles and Ovals toolbar.” Click the Add button. Click Close to close the selection dialog. | For quick access to the arcs and segments tools, we need to add the Circles and Ovals toolbar to the Drawing toolbar.

We don't really need the Ellipse tool any longer as it is included in the Circles and Ovals toolbar. Uncheck the Ellipse tool.

To draw an arc or segment, select one of the tools from the Circles and Ovals toolbar you just added. Click and drag to create a containing circle or oval. Release the mouse button. Click in the circle or oval where you want the arc or segment to begin. Move the mouse around the circle or oval to create the arc or segment. Click a second time to create the end point for the arc or segment. The status bar will show you the angle from center of the points as you move around the circle or oval. This can help you create accurate and precise arcs and segments. | To draw an arc or segment, select one of the tools from the Circles and Ovals toolbar you just added.

- | A curve is a bent line rather than a segment of a circle or oval. To draw a curve, select the curve tool from the line toolbar. Click on the start point and drag to draw a line. Release the mouse button at the peak point for your curve. Move the mouse to bend the line to the point where you want the curve to end. Double-click to complete the curve. | + | A curve is a bent line rather than a segment of a circle or oval. To draw a curve, select the curve tool from the line toolbar.

A Bezier curve is a smooth curve with a start point, an end point, and two control points. The mathematics behind the Bezier curve is beyond the scope of this article, but you don't need to understand the math in order to draw one. | A Bezier curve is a smooth curve with a start point, an end point, and two control points.

- | Since not all things are created from straight lines, ellipses, and circles, the creators of Draw gave us more tools for creating objects. A polygon can create an object with more than four sides. Arcs and segments gives us parts and segments of a circle or ellipse. Curves give us the ability to bend a line into different shapes. With these extra tools in hand, Draw lets you create more advanced images for your documents. | + | Since not all things are created from straight lines, ellipses, and circles, the creators of Draw gave us more tools for creating objects.
