Try this code in your editor

Now change the code to this:

What shape does this draw?

Remember
360 ÷ 90 =4 and 4 x 90 =360
360 ÷ 5 = 72 so 5 x 72 = 360
360 ÷ 6 = 60 so 6 x 60 = 360
360 ÷ 8 = 45 so 8 x 45 = 360
360 ÷ 10 = 36 so 10 x 36 = 360

What other regular shapes can you draw?

 

Can you make the feature image for this post. I’ve duplicated my sprite a few times.

Tips

• Think about co-ordinates.
• Duplicate sprites
• Give your sprites a different costume so you can tell them appart.
• Do you need the  erase block all in each sprites code (it might be a problem, why?).

 

If you work it out you can add the scratch project to your e-Portfolio, here is how:

We can all draw angles with scratch, but can we add a wee square to a right angle and arc to acute & obtuse angles?

1. Check you can draw a line. Try this bit of code, change the x & y options for both go to blocks a few times.

2. Draw a circle, remember this is not a real circle, but if you make a polygon with enough sides it looks like a circle.

Next can you alter the code to draw half a circle. Then close the loop to make a semi-circle?

If you can manage that you might be able to draw some angles.
