Scratch Angle Challenge

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.
