How to Draw a Pentagon Using a Compass and Ruler
1 – The first step in making a pentagon is to
make a circle, with a diameter the size of
the pentagon, with your compass.
2 – Next you need to find the center lines,
both horizontal and vertical.
a – Using your compass, draw an arc
with the center on point A and the
diameter of point A to B.
b - Using your compass, draw another
arc centered on point B and the
diameter of point B to A.
c – Draw a line between the arc
intersections C & D.
d - Using your compass, draw an arc
with the centered on point E and the
diameter of point E to F.
e - Using your compass, draw another
arc with the centered on point F and the
diameter of point E to F.
f – Draw a line between the arc
intersections G & H.
G – Erase the arcs and trim the center
lines to the circle.
The intersection of these two lines is the center of
the circle, point I.
