13. We use a compass for drawing circles.
14. If you make a mistake you can correct it with an ___________
15. but only if you were drawing with a ________________
16. You can’t draw a 50º degrees angle without a ________________

Activity 3: Follow the steps to draw a polygon.
a) Use ruler and pencil todraw a 8 cm segment
b) Take the compass and
measure a 6 cm radius on
the ruler
c) Place the spike of the
compass on one end of the
segment and draw an arc
over the middle
d) Do it again from the
other side
e) Now connect the
intersection of the arcs
with the ends of the
segment.
Your drawing goes here
What sort of polygon is this? _______________________________

Activity 5: The pentagon and the 5-pointed star
Follow the steps to complete the drawing:
1. Take the first circle and draw a diameterwith pencil and ruler (a straight line acrossthe middle)
2. You need to divide the circle in five equalangles (360º : 5 = 72º) → Use theprotractor to draw a 72º angle with thevertex in the centre
3. Use the compass to take the measure ofthe sector and “copy it” around the circle
4. Use the ruler to draw segments from everyvertex to the next one. You just drew aregular pentagon
5. Repeat the process but this time, draw thesegments skipping one vertex to form afive-pointed star
5. Repeat the process but this time, draw thesegments skipping two vertices to form astar
5. Repeat the process but this time, draw thesegments skipping two vertices to form astar

Activity 7: For this exercise you will work in pairs.• Before starting: take a good look at the steps in activity 6 and your drawing.• DO NOT SHOW these to your partner.• One partner will have to describe his/her drawing to the other. Use your own words. •••• The other partner will try to draw it following the instructions.

Activity 8: The contest (part one)
A very popular rock band has organised a design contest. They want you to send
them designs they can use for their next album cover. Use compass, protractor and
ruler to design a shape containing polygons and stars in the same circle.
See some examples in the presentation.
