Answer 1

Answer:

I'll explain you this.

Step-by-step explanation:

So for 90° first draw a line as base. Then draw a semi circle at any end of the line. Then place the compass at the joining point and mark an arc on the semi circle. Similarly, place the compass on the arc you made and again mark an arc. Now on the two arcs( that are on the upper part of the semi circle) draw arc respectively that intersects each other. That'll be a 90° angle.

So for 45°, place the compass at 90° and draw an arc, then place the compass at first arc and mark an arc which intersects the previous arc. Join the arcs. This will be the 45° angle.

For 30°, place the compass at 90° and 0° and mark arcs. This will be the 30° angle.

For 60°, place the compass at 30° and 90° and mark arcs that intersect each other. That'll be the 60° angle.

120° is already made with the second arc. (You can confirm this using a protractor.)

180° is the straight line.

Note.

You have to do the same semi circle procedure in

the making of every angle.
