<p>[QUOTE=&quot;cpm9ball, post: 2640718, member: 24633&quot;]I have always enjoyed math, and mechanical drawing, drafting &amp; AutoCAD have been my hobbies going back to the 7th grade. Measuring the degree of these angles isn&#039;t rocket science to me. I use my &quot;mind&#039;s eye&quot; to calculate the measurements. A horizontal line through the center of the circle represents 0 &amp; 180 degrees. A vertical line represents 90 &amp; 270 degrees. A diagonal line from corner to opposite corner is 45 to 225 and 135 to 315, respectively. I just imagine that the circular opening of the 2x2 is the face of a clock and the hours and minutes represent the degrees of an angle. You don&#039;t have to be that precise in measuring the degree of rotation of a coin. It&#039;s not like pointing at the moon and ending up on Jupiter.</p><p><br /></p><p>Maybe this will help you. Try making a template out of one 2x2 for each denomination - 1c, 2c, 3c, 5c, 10c, 20c, 25c, 50c, small $ &amp; large $ - and use it whenever the need arises.</p><p><br /></p><p>Chris[/QUOTE]</p><p><br /></p>
