Answer:

1. Construct a right angle ABC

2. Put the sharp end of your compass at point B and make one arc on the line BC and another arc on line AB

3. Without changing the width of your compasses, put the sharp end of the compasses at the arc on BC and make an arc within the lines AB and BC. Do the same at the arc on AB and make sure that the second arc intersects the first arc. Name the point of intersection as P.

4.Draw a line from point B to the points of intersection of the 2 arcs. This line bisects the ∠ABC

On measuring =∠PBC=45°
