Formulas and Measurements
- Set dividers from Points B to E.
- Set dividers at Points B and F.
- Figure 2 Set dividers and draw arcs on both legs Apex / of the angle.
- To divide Line A-B into an equal number of divisions, in this case 10, draw a line from A to C (this is the line with the known source for equal divisions) Place a straight edge from A to C and from point C draw a 90 degree line to Point B.

Bisect the distance from C to D to form Point E.
Set dividers from Points B to E.
Using point E as an Apex, mark a point on the A-C line to form Point F.
Set dividers at Points B and F.
Using Point B as an Apex, mark a point on the arc to form Point G.
From A to G will be one fifth of the Quarter Circle.

Dividing a line into an equal number o divisions from =figure 4 a known source.
To divide Line A-B into an equal number of divisions, in this case 10, draw a line from A to C (this is the line with the known source for equal divisions) Place a straight edge from A to C and from point C draw a 90 degree line to Point B.
Draw 90 degree lines up from this line through to points on the A-C line to points on the A-B line.
