Open in App
Solution

Step 1. To construct an angle of measure first we have to construct an angle BAW=90°.(Or we can choose any other terms for the angle)

Step 2. As we know that 45 is half of 90 so lets bisect bisect BAW. For that taking P and T as centre draw arcs in between the right angle.These arcs will intersects at a point say point U.

Step 3. Now join A and U and produce to V. This AV is the angle bisector of the angle BAW. Thus BAV=45°.
