Let A B C D E, be the propoſed Pentagon,
11Fig. 15. wherein draw the Line B D which will be paral-
lel to A E, becauſe the Pentagon is a regular
one.
11Fig. 15. wherein draw the Line B D which will be paral-
lel to A E, becauſe the Pentagon is a regular
one.
Now find the Repreſentation of the ſaid 2242.
Lines A E and B D, and you will have the Re-
preſentation of four of the Corners of the Pen-
tagon; and to determine the Repreſentation of
the fifth Corner, find the Appearance of 3343. Line drawn from C to E, which in this Example
is parallel to A B, which is ſuppoſed parallel
to the Baſe Line.

Example II.
Draw the Line O G thro’ the Eye O parallel to
the Side A D, cutting the Horizontal Line in G;
likewiſe draw O F parallel to the Side A B cutting
the Horizontal Line in F, and produce the Sides
of the Parallelogram, and the Lines dividing it,
to the Baſe Line; then from the Points wherein
A D and C B, and the Lines parallel thereto
cut the Baſe Line, draw Lines to the Point G.
Alſo from the Points wherein A B and C D and
their parallels cut the ſaid Line, draw Lines to
the Point F, whoſe Interſections with
the Side A D, cutting the Horizontal Line in G;
likewiſe draw O F parallel to the Side A B cutting
the Horizontal Line in F, and produce the Sides
of the Parallelogram, and the Lines dividing it,
to the Baſe Line; then from the Points wherein
A D and C B, and the Lines parallel thereto
cut the Baſe Line, draw Lines to the Point G.
Alſo from the Points wherein A B and C D and
their parallels cut the ſaid Line, draw Lines to
the Point F, whoſe Interſections with
