The Pen blocks are added to the Code tab. They are colour-coded green and are used to draw
shapes, design patterns, and adjust the colour and thickness of the lines or drawings created
by the sprite, not the shape itself.
The lets you change the pen's colour.
The block lets you adjust the pen's thickness by typing a number in the box.
DRAWING A POLYGON
Polygons are 2D shapes with three or more straight lines and angles. Examples of polygons
are triangle, square, rectangle, quadrilateral, pentagon, octagon, etc.
Triangle Square Pentagon
(3 sides) (4 sides) (5 sides)
To draw polygons in Scratch, follow these basic guidelines:
Determine the number of sides: Know how many sides the shape has. This number is
used in the Repeat block. For example, use Repeat 3 to draw a triangle and Repeat 4 to
draw a square.
Draw and turn: Each time you use the Repeat block, the Sprite will draw a line and turn at
each corner.
Calculate the angle: Find the angle for each corner by dividing 360 degrees by the number
of sides. For instance, to draw a triangle, divide 360 by 3 (the number of sides), resulting in
a 120-degree turn.
Look at these polygons can be made using repeat.
Drawing a Square
To draw a square in scratch, arrange the blocks as shown below:
