                        DRAWING A LINE IN SCRATCH


                 Let's learn how to draw a line in Scratch. Look at the code and its output.

                 The line appears on the stage.

                 To view the line in full screen, click on Full Screen Control button        on the top right corner
                 of the stage.

                        DRAWING POLYGONS IN SCRATCH


                 Polygons are 2D shapes with three or more straight lines and angles. Examples of polygons
                 are triangle, square, rectangle, quadrilateral, pentagon, octagon, etc.






                  Equilateral   Square     Pentagon     Hexagon     Heptagon      Octagon     Nonagon      Decagon
                   Triangle    (4 sides)    (5 sides)   (6 sides)    (7 sides)    (8 sides)   (9 sides)   (10 sides)
                   (3 sides)
                 To draw polygons in Scratch, you must remember a few thumb rules. These are as follows:

                    You must know the number of sides in the shape. This is the value to be given in Repeat
                   block. For example, you give Repeat 3 to draw a triangle and 4 to draw a square.

                    Each time a Repeat block is used, you draw a line and turn at a corner.

                    You must know the degree of the angle at the corner. It is very easy to calculate this. Just
                   divide 360 by the number of sides in the shape. For example, to draw a triangle, the turn
                   will be 360/3 (sides of the triangle) = 120.


                                                                                         Creating Shapes in Scratch  99
