02

Step 2. Concept used.

Draw a line PQ

Take a radius from the line PQ and draw an arc and named that point M.

From M point draw another arc with same radius and named that point as N.

Join the point Pand N,

then 鈭�NPQ=60掳

03

Step 3. Use compass.

By using compass and straightedge,

draw 45,鈭�60,鈭�90掳 other than 30 degrees.

Therefore, angles 45,鈭�60,鈭�90掳 other than 30掳.
