Question

Is there an easy way to know whether an angle can be constructed using ruler and compass?​

Answer 1

Answer:

Yes

Step-by-step explanation:

Draw a line

Open compas less than half draw arc semi circle than Go at the point where you started the arc then again draw semi circle arc then keep compass on second semi circle arc start or origin then again do arc then create a line joining three points that's 30 °

Then

open the compass to the same dimensions as our original line.

place the point of the compass on one end of the line and draw an arc.

repeat this at the other end and the arcs should intersect where the tip of the triangle should be

Thenthe exam you will have a ruler and a pair of compasses, which you can use to construct a 60 degree angle by drawing two arcs. You can then draw two more arcs to bisect that 60 degree angle and make a 30 degree angle.
