Create Polygons and Beziers Polygons, Beziers and Symmetric shapes are used to define the shape (or path) of a vector object. A vector object is a computer graphic with a shape defined by its path which is determined by the connections between points. A vector object’s stroke color follows the path and its fill color occupies the area inside the path. Properties of vector objects, including the position of its points can be edited and vector objects can be resized without losing resolution.     Polygons
A Polygon is a plane figure that is bounded by a closed path, composed of a finite number of sequential line segments. The straight line segments that make up the boundary of the polygon are called its edges or sides and the points where the edges meet are the polygon's vertices or corners. The interior of the polygon is its body.     Polylines
A Polyline defines a set of connected straight line segments. Typically, polylines define open shapes. A straight line is a polyline that contains a single line segment.     Beziers
A Bezier curve is defined by four control points, known as knots. Two of these are the end points of the curve, while the other two effectively define the gradient at the end points. These two points control the shape of the curve. The curve is actually a blend of the knots. This is a recurring theme of approximation curves; defining a curve as a blend of the values of several control points.     Cusp node
A cusp node is where two curves or lines meet. If you want two lines or curves to meet at a sharp angle, a cusp node is what you need.     Symmetric node
The two control points that control the gradient of the selected node are symmetric to each other. The result is not a sharp node, but a curve. To widen the curve, grab one of the control points and pull outward. With a symmetric node, both control points behave the same way, lengthening by equal amounts. The two control points always form a straight line.     Asymmetric node
An asymmetric node also converts a sharp node to a curve. The real difference between a symmetric and asymmetric node is the way in which the control points behave. With the asymmetric node, the length of the two control points are not linked. You can pull one side of the curve out more than the other. The angle of the two control points is still linked however- they remain a straight line when one or the other is moved up or down.     Symmetric Shapes
The Symmetric Shape tool is used to draw rotationally symmetric shapes. It's grouped with the n-sided Polygon, n-pointed Star, n-pointed Cross and Symmetric Shape tools. The Symmetric Shape tools have 2 or more points of symmetry (the small yellow squares). They can move in any direction relative to the center point.
