## 30 Aug The 30-60-90 Challenge

Goal: Draw a 30 and 60 degree angle using only a framing square. Twelve sided columns were used in many historical homes. How did carpenters then (and now) use the framing square to create the needed angles of 30 and 60 degrees?

Materials allowed: Paper, pencil, framing square, and your knowledge about the ratios of the sides in a 30-60 right triangle.

Hint: Draw a line 16” long (or any length you wish). Use this as a hypotenuse of the framing square.
