To begin with, how many sides does a
Pentagon have?
                                   #[N]

@Answer 1, 5

@Feedback 0, ?
#bNo#. If you see #bpent# this usually means the number #bfive#
is involved (the Pentagon building in the United States has five sides).
Now move on to say what your first step will be when drawing a pentagon.

@Feedback 1
#bRight#. Now move on to say what your
first step will be when drawing a pentagon.

@KeyPointFeedback 0,Wrong option
#bNo#.  When drawing a regular polygon with more than four
sides, you should always start by #bdrawing a circle#.

@Answer 0.5,  compasses

@Feedback 0, ?
#bNo#.  You should use a #bpair of compasses# to draw
the circle. What will you do once you have done this?

What next?
@at ,+3
#[K]
@keyPointAnswer 1,403,≈ 360* by the number of polygon sides



@KeyPointFeedback 0, WrongOption
#bNo#. Next you should #bdivide 360░ by the#
#bnumber of sides# of the polygon you are drawing.

@Answer 1, 360, 5, 72

@Feedback 0.5, 360, 5, ?
Well you were right to say you should divide
360░ by 5, but the result should be 72░.
Now, what will be your next step?

@Feedback 0, ?,?,?
#bNo#.  You should divide the number of degrees in a circle (360)
by the number of sides of the shape you are drawing (5).  This will
give you the result 72░.  Using this result, what will be your next step?

@Feedback 1
#bRight#.  What will be your next step?

@question

#[K]
@keyPointAnswer 1,404,mark off the circle




@KeyPointFeedback 0, WrongOption
#bNo#. You should now mark off the circle at 72░ intervals.

@Answer 0.5,  protractor

@Feedback 0, ?
#bNo#.  You should use a #bprotractor# (placed at the
circleÆs #bcentre#) to measure the 72░ intervals around
the circle. What is the final step in drawing the pentagon?

You should always use a #bruler#
to draw straight lines.

@Feedback 0.5
That's right.  You've completed the pentagon.
