                 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.

                                   (3 sides)          (4 sides)         (5 sides)          (6 sides)

                                   (7 sides)          (8 sides)         (9 sides)          (10 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 command 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.
                 Look at these polygons that can be made using repeat command.

                            Square                     Repeat 4 Move 100 Steps Turn 90 degrees


                            Pentagon                   Repeat 5 Move 100 Steps Turn 72 degrees
