# To construct a regular hexagon, what measure would be necessary for each interior angle? Construct an angle of that measure.

To determine

The measures for each interior angle necessary to construct the regular hexagon and construct an angle of that measure.

Explanation

Formula used:

The formula of measure of interior angle of regular polygon of n side is given by,

I=(nâˆ’2)n180Â°

Given:

The given polygon is hexagon.

Calculation:

For hexagon,

n=6

Substitute 6 for n in the above mentioned formula to calculate the measure of interior angle.

I=(6âˆ’2)6180Â°=46Ã—180Â°=120Â°

Thus, the measures for each interior angle necessary to construct the regular hexagon is 120Â°.

Now, construct an angle of measure 120Â°.

Approach:

Consider a line AB as shown below.

Figure (1)

Take point A and B as center and construct two circle of radius AB and mark the intersection points as shown below
