Question

What should be done to draw an angle of 45° using a pair of compass and ruler?

Answer 1

Step-by-step explanation:

45 Degree Angle

Construct a perpendicular line.

Place compass on intersection point.

Adjust compass width to reach start point.

Draw an arc that intersects perpendicular line.

Place ruler on start point and where arc intersects perpendicular line.

Draw 45 Degree Line.

Answer 2

(QAR) = 45°

We can construct a 45° angle either by bisecting a right angle.

Step 1 : Draw a line PQ.

Step 2 : Bisect the line PQ using compass.

Step 3 : Join SA.

Step 4 : Bisect the arc SQ.

Step 5 : Join RA.

Result:

angle RAQ = 45° is the required angle.
