Question

write logo commands to draw these polygon

Answer 1

to triangle repeat 3 [fd 50 lt 120] end

triangle

to square repeat 4 [fd 50 lt 90] end

square

to rectangle fd 60 rt 90 fd 40 end

rectanle

to octagon repeat 8 [fd 50 lt 45] end

octagon

Answer 2

The logo commands for drawing the given polygons as follows :

• As the full angle is 360 degrees so external angles will be 360/n where n is number of sides.
• So fd will be of some arbitrary length and rt or lt of 360/n. Repeat will be of n times. So the commands as follows.
• Octagon :-  repeat 8 [fd 50 rt 45]
• Square :-  repeat 4 [fd 50 rt 90]
• Triangle :-  repeat 3 [fd 50 rt 120]
• Rectangle :- fd 50 <- rt 90 <- fd 50 <- rt 90 <- fd 50 <- rt 90 <- fd 50
