To draw polygons in Scratch, you must remember a few thumb rules. They are:
• 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 check font 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. Just divide
360 by the number of sides in the shape to get the degree of the angle. For example, to draw
a triangle, the turn will be 360/3 (sides of the triangle) = 120.
Look at these polygons can be made using repeat.
i + DRAWING A SQUARE
To draw a square in scratch, arrange the blocks as shown below.
Info Byte
A loop is a process that instructs a computer to repeat a set of commands for a specified
number of times.
Look how these polygons can be made using Repeat.
