Question

Draw the given angles using a protractor. Then, bisect the angles using a ruler and compasses. 70°. Steps of construction​

Answer 1

Steps of construction :-

Step I - Draw a ray OA as shown in figure.

Step II - With the help of a protractor construct an angle AOB measure 70.

Step III - With a centre O and a convenient radius draw an arc cutting sides OA and OB at P and Q respectively.

Step IV - With centre P and radius more than half PQ , draw an arc.

Step V - With centre Q and the same radius, as in the previous step ,draw another arc intersecting the arc drawn in the previous step at R .

Step VI - Join OR and produce it to form ray OX .

The angle AOX and angle BOX so formed are equal.
