Draw the line M N 3 1/4 inches long and draw two angles A O D and E F G about 30 degrees and 60 degrees respectively.

Draw R S equal in length to M N and with R as a vertex and RS as one side construct an angle equal to A O D. In a similar manner construct at S an angle equal to E F G. Draw lines from R and S through the two established points until they meet at T. The triangle R T S will be the required triangle.


Draw the pencil lines and put in the lettering as in plates already drawn.


In inking Plate V, follow the principles previously used and do not make certain lines dotted until sure that they should be dotted.

After inking the figures, ink in the border lines and the lettering as already explained.
