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.
