Question

How to make 18 degree angle from compass ?

Answer 1

I believe you need to construct a regular pentagon (directions can be found using a google search).

drawing in the diagonals of the pentagon forms the familiar 5-pointed star, each point is 36 degrees ... bisect that angle.

Answer 2

Answer:

The construction of the angle is discussed below :

Step-by-step explanation:

To draw an 18 degree angle using compass, we need to first construct pentagon whose all sides are of equal length.

Now, in a regular pentagon measure of all the angles are same because all its sides are equal.

So, each angle is of measure 36 degree

Now, we can easily bisect any angle of the pentagon by using a compass in order to get the required angle of measure 18 degree.

Hence, this is the required way to get an 1 degree angle using a compass
