Question

construction of an angle of measure 90°,45° with the help of compass​

Answer 1

Answer:

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.

Step-by-step explanation:

We can construct a 90º angle either by bisecting a straight angle or using the following steps.

Step 1: Draw the arm PA.

Step 2: Place the point of the compass at P and draw an arc that cuts the arm at Q.

Step 3: Place the point of the compass at Q and draw an arc of radius PQ that cuts the arc drawn in Step 2 at R.
