there are 6 right angles in a pentagon.

A pentagon is a five side figure. A regular pentagon has sides of equal length and the internal angles are all the same.

It would help you if you remembered the following:

The exterior angle of a regular polygon = 360 degrees /no. of sides. So for a regular pentagon, the exterior angles are = 360/5 which equals 72 degrees.

The interior angles of a regular polygon = 180 degrees - the exterior angle. So for a regular pentagon the interior angles are all 180 - 72 = 108 degrees.

Do you mean the sum of the internal angles of a polygon?

The sum of the interior angles can be shown as (2n-4) right angles where n is the number of sides of the polygon.

In the case of a pentagon the sum of the interior angles is 6 right angles or 540 degreess because n = 5
Since the pentagon is regular each interior angle is 108 degrees i.e 540/5 degrees.

zero. The angles in a regular pentagon are 108 degrees.

I don't think there are any right angles in a regular pentagon? It's known as a golden pentagon I think.

i genuinely labored this out as quickly as. the version between the perspective and a hundred and eighty stages is comparable to 360 stages - the style of angles. So on condition that there are 5 angles in a pentagon, the version between the perspective and a hundred and eighty stages is (360/5) = seventy two stages. So the perspective is 108 stages. in addition, the version between the perspective in a hexagon and a hundred and eighty stages is 60 stages, so the perspective is one hundred twenty stages.
