Question

How to construct an angle of 135 degree​

Answer 1

• Draw any line segment of the required length and name it. (for example AB)
• Now use compass and open it to any convinent radius. And with A as center, draw an arc which cuts line segment AB at a small length (2.5cm) and name it D.
• Again use compass and open to the same radius. And with D as center, draw an Arc which cuts first arcs at Z (the arc drawn).
• Again use compass and open to the same radius (as of 2nd point). And with Z as center draw an arc which cuts first arc at C (the arc drawn).
• Again use compass and open it to the same radius (as of 2nd point). And with Z as center, draw two arcs cuts each other at E.
• Join OE and extent it to Q.
• The angle will be 90°.
• Extend BO to Z.
• Again use compass and open it to any convinent radius. And with O as center, draw an arc which cuts line segment AB at P and 0A at Q.
• Again use compass and open to radius (as 10th point). With P as center, draw two arcs which cuts each other at point F.(the arc drawn)
• Join OF and extend to E.
