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.
Equilateral Square Pentagon Hexagon Heptagon Octagon Nonagon Decagon
Triangle (4 sides) (5 sides) (6 sides) (7 sides) (8 sides) (9 sides) (10 sides)
(3 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 block 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.
