To construct an angle of 30⁰ as shown in the diagram the first step is to :

To construct an angle of 30⁰ , we construct the angle bisector of _____________

The measure of an acute angle is________

What type of angle is 60 degree ?

Arrange the steps in correct order to make the construction in the diagram:-

1. With centre P and radius more than half of PQ, draw an arc in the interior of

2.Join OS and product it to any point C.

3. With centre R and the same radius, draw another arc intersecting the arc in step III at S.

4.Draw by using the steps mentioned above.

5.With centre O and any convenient radius draw an arc cutting OA and OB at P and R respectively.

Which of the following step is Incorrect to construct an angle of as shown in the figure below:

Perpendicular bisector of a chord of  a circle  is _____________.

Arrange the steps in correct order to make the construction in the diagram:-

1.Draw a ray OA.

2. With R as centre and the same radius, draw an arc

3. With O as centre and any convenient radius, draw an arc, cutting OA at P.

4. With S as centre and the same radius,draw an arc, cutting the arc drawn in step V at T

5. Draw OT and produce it to B.

6. With R as centre and the same radius as in steps II and III, draw an arc, cutting the arc drawn in step III at S.

7. With P as centre and the same radius, draw an arc cutting the arc drawn with O as centre at R..
