DRAWING SHAPES USING CONTROL BLOCKS

The shapes can also be drawn using different Control blocks.

REPEAT BLOCK

If you want to repeat a block of code a fixed number of times, the Repeat block is used.
With the Repeat block, you can draw Polygons. Examples of polygons are triangle, square,
pentagon, hexagon, heptagon, octagon, nonagon, decagon, etc.

Look at these polygons that can be made using the repeat block.

Polygon Command

Triangle Repeat 3 [Move 100 Steps → Turn 120 degrees]

Square Repeat 4 [Move 100 Steps → Turn 90 degrees]

Pentagon Repeat 5 [Move 100 Steps → Turn 72 degrees]

Hexagon Repeat 6 [Move 100 Steps → Turn 60 degrees]

Heptagon Repeat 7 [Move 100 Steps → Turn 51 degrees]

Octagon Repeat 8 [Move 100 Steps → Turn 45 degrees]

Nonagon Repeat 9 [Move 100 Steps → Turn 40 degrees]

Decagon Repeat 10 [Move 100 Steps → Turn 36 degrees]

To draw polygons in Scratch, you must remember three points:

1. You must know the number of sides in the shape. This is the value to be given in repeat
block.

2. Each time a repeat command is used, you draw a line and turn at a corner.

3. 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.
