Question

Construct an angle of 90° .Construct its angle bisector. Write measures of both angles​

Answer 1

Explanation:

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°

steps

* draw a line segment

* take a point and draw an arc

* draw 60° and 120°

* bisect the middle one

* it will be the 90°

* bisect the angle between 60° and 90°

* angle form will be 45°

hence prooved
